La aplicación práctica de esta aleación madre cuaternaria es para el afino de grano del aluminio y sus aleaciones . CAMPO DE APLICACIÓNMore specifically, the object of the invention focuses on a novel aluminum alloy (also called "mother alloy") containing aluminum, zinc, titanium and carbon, which is obtained or synthesized by the fusion of aluminum and the subsequent addition of titanium, zinc and carbon. After the desired composition is obtained and homogenized, the molten alloy is cast by casting as desired.

The practical application of this quaternary mother alloy is for the grain refining of aluminum and its alloys. SCOPE
El campo de aplicación de la presente invención se encuentra dentro de la industria metalúrgica del aluminio, concretamente para el afino de grano del aluminio y sus aleaciones. ANTECEDENTES DE LA INVENCIÓNThe field of application of the present invention is within the metallurgical industry of aluminum, specifically for the grain refining of aluminum and its alloys. BACKGROUND OF THE INVENTION
Como es sabido, el afino de grano del aluminio y de sus aleaciones es una práctica industrial ampliamente utilizada. El afinador de grano comercial estándar es la aleación madre de Al-Ti-B, que contiene partículas de TiB2 y que se encuentra disponible comercialmente con diferentes contenidos de Ti y de B. La aleación madre más comúnmente utilizada es el Al- 5%Ti-l%B en forma de varilla (composiciones en % en peso, si no se indica otra cosa) .As is known, the refining of grain from aluminum and its alloys is a widely used industrial practice. The standard commercial grain tuner is the Al-Ti-B mother alloy, which contains TiB 2 particles and is commercially available with different Ti and B contents. The most commonly used mother alloy is Al-5% Ti-l% B in the form of a rod (compositions in% in weight, if not indicated otherwise).
Se sabe que las aleaciones madre de Al-Ti-B son eficaces para aplicaciones generales, aunque causan los siguientes defectos en ciertas aplicaciones especificas, debido a la presencia de partículas gruesas y aglomeraciones de TiB2:Al-Ti-B mother alloys are known to be effective for general applications, although they cause the following defects in certain specific applications, due to the presence of coarse particles and TiB 2 agglomerations:
- poros en las hojas de aluminio,- pores in aluminum sheets,
- estrias y defectos superficiales en chapas y productos similares que requieren un buen acabado superficial, grietas de rechupe y agrietamiento en lingotes, especialmente en algunas aleaciones de alta resistencia, como 7010/7050, que se utilizan en la industria aeronáutica. Además, se necesita adicionar mayores cantidades de Al-Ti-B para el afino de grano de aleaciones para alta temperatura que contienen Cr y Zr, los cuales se cree que son un veneno para el afinador de grano convencional de Al-Ti-B. A la vista de la existencia de los problemas antedichos en un amplio campo de aplicaciones especificas, el inventor principal Dr. Abinash Banerji desarrolló un afinador de grano ternario Al-Ti-C libre de boro, que contiene partículas de TiC, que forman núcleos de granos de aluminio (Dr. Abinash Banerji, Tesis Doctoral Universidad Técnica de Berlin, 1987).- Stretch marks and surface defects in sheets and similar products that require a good surface finish, crack cracks and ingot cracking, especially in some high strength alloys, such as 7010/7050, which are used in the aeronautical industry. In addition, larger amounts of Al-Ti-B need to be added for grain tuning of high temperature alloys containing Cr and Zr, which are believed to be a poison for the conventional Al-Ti-B grain tuner. In view of the existence of the above-mentioned problems in a wide range of specific applications, lead inventor Dr. Abinash Banerji developed a boron-free Al-Ti-C ternary grain tuner, which contains TiC particles, which form nuclei of aluminum grains (Dr. Abinash Banerji, Doctoral Thesis Technical University of Berlin, 1987).
El procedimiento de producción de este afinador de grano ternario se patentó posteriormente en 1985 (Patentes U. S. A. n° 4748001 y 4842821, patentes de la UE n° 0214220 (Reino Unido), 0214220 (Francia), 0214220 y P3679263.2 (Alemania), 0214220 (Paises Bajos), patente australiana n° 595187, patente canadiense n° 1289748, patente japonesa n° 2121452, patente noruega n° 167589) . Durante más de una década y hasta ahora, el afinador de grano de Al-Ti-C se ha producido comercialmente en todo el mundo por varios fabricantes, aunque las aleaciones madre de Al-Ti-C se encuentran disponibles con distintos contenidos de Ti y C. Sin embargo, la aleación madre comúnmente utilizada tiene una composición de aproximadamente Al-3%Ti-0, 2%C.The production process of this ternary grain tuner was subsequently patented in 1985 (US Patents No. 4748001 and 4842821, EU Patents No. 0214220 (United Kingdom), 0214220 (France), 0214220 and P3679263.2 (Germany), 0214220 (Netherlands), Australian Patent No. 595187, Canadian Patent No. 1289748, Japanese Patent No. 2121452, Norwegian Patent No. 167589). For more than a decade and until now, the Al-Ti-C grain tuner has been commercially produced worldwide by several manufacturers, although Al-Ti-C mother alloys are available with different Ti and C. However, the commonly used mother alloy has a composition of approximately Al-3% Ti-0.2% C.
A pesar de ser una práctica industrial durante más de una década, el afinador de grano de Al- Ti-C disponible hasta ahora no ha sido capaz de resolver de forma eficaz los problemas asociados con el afinador de grano de Al-Ti-B convencional, ya que se necesita adicionar cantidades mayores para obtener un nivel de tamaño de grano similar al obtenido con el afinador de grano de Al-Ti-B comercial.Despite being an industrial practice for more than a decade, the Al-Ti-C grain tuner available so far has not been able to effectively solve the problems associated with the conventional Al-Ti-B grain tuner , since larger quantities need to be added to obtain a level of grain size similar to that obtained with the commercial Al-Ti-B grain tuner.
Visto lo que antecede, el objeto de la presente invención se centra en desarrollar otro afinador que supera el rendimiento de los afinadores de grano de Al-Ti-C, disponibles comercialmente hasta ahora, y que resuelva de forma eficaz los problemas bien conocidos asociados con el afinador de grano de Al-Ti-B convencional, debiendo señalarse que, por parte del solicitante se desconoce que se haya producido ninguna aleación ni ninguna aleación madre de base aluminio que contengan cinc, titanio y carbono y que muestren capacidad de afino de grano, tal como la que reivindica la presente invención. EXPLICACIÓN DE LA INVENCIÓNIn view of the foregoing, the object of the present invention is focused on developing another tuner that exceeds the performance of the Al-Ti-C grain tuners, commercially available so far, and that effectively resolves the well-known problems associated with Conventional Al-Ti-B grain tuner, it should be noted that it is not known by the applicant that there has been no alloy or any aluminum alloy base alloy containing zinc, titanium and carbon and showing grain refining capacity , such as that claimed by the present invention. EXPLANATION OF THE INVENTION
De forma concreta, el afinador de grano objeto de la invención, se produce del modo siguiente:Specifically, the grain tuner object of the invention is produced as follows:
En un horno se funde aluminio puro disponible comercialmente (generalmente aluminio 99,7 %), a las temperaturas normales de fusión del aluminio (aproximadamente 700-10000C) , se añade la cantidad necesaria de titanio, en forma de esponja de titano o de chatarra de titanio (por ejemplo, virutas) . Otra fuente de titanio puede ser una sal que contenga titanio, por ejemplo, K2TiF6. En este último caso, inicialmente se puede producir una mezcla binaria de Al-Ti, mediante la adición de la cantidad requerida de sal al aluminio fundido, y después de que la mezcla binaria de Al-Ti esté lista y de que la escoria se sea retirada de la superficie fundida, puede comenzar el proceso posterior. De forma alternativa, también se puede fundir directamente una aleación madre de Al-Ti.In an oven available pure aluminum melts commercially (generally 99.7% aluminum) at normal melt temperatures of aluminum (about 700-1000 0 C), the necessary quantity of titanium is added as titanium sponge or of titanium scrap (for example, chips). Another source of titanium may be a salt containing titanium, for example, K 2 TiF 6 . In the latter case, initially a binary mixture of Al-Ti can be produced, by adding the required amount of salt to the molten aluminum, and after the binary mixture of Al-Ti is ready and the slag becomes removal of the molten surface, the subsequent process can begin. Alternatively, an Al-Ti mother alloy can also be melted directly.
A continuación, se añade a la masa fundida cinc puro o una aleación que contenga cinc (por ejemplo, una aleación Zn-Al) seguido de polvo de carbono, que puede ser grafito o carbono amorfo. El proceso habitual es que la adición del titanio vaya seguida del cinc y del carbono, aunque la secuencia de adición de los elementos no supone una limitación para la invención. La adición puede ser de los tres elementos juntos o de uno después de otro. El tiempo de mantenimiento necesario de la aleación en el horno ("holding") , después de que se han añadido todos los elementos, es habitualmente de entre 30 y 60 minutos para que la completa reacción de los tres elementos produzca las partículas de carburo ternarias de titanio, cinc y carbono. El tiempo de mantenimiento dependerá de la composición de la colada, del volumen de la misma, de la temperatura de fusión y del tipo de horno. En el caso de fusión por inducción, un efecto de agitación puede reducir el tiempo de mantenimiento.Then, pure zinc or an alloy containing zinc (for example, a Zn-Al alloy) is added to the melt followed by carbon powder, which may be graphite or amorphous carbon. The usual process is that the addition of titanium is followed by zinc and carbon, although the sequence of addition of the elements does not constitute a limitation for the invention. The addition can be of the three elements together or one after the other. The necessary maintenance time of the alloy in the furnace ("holding"), after all the elements have been added, is usually between 30 and 60 minutes for the complete reaction of the three elements to produce the ternary carbide particles of titanium, zinc and carbon. The maintenance time will depend on the composition of the laundry, its volume, the melting temperature and the type of oven. In the case of induction melting, a stirring effect can reduce the maintenance time.
La aleación madre obtenida se moldea por colada mediante el procedimiento habitual en lingotes ("waffles"), bloques o barras que se pueden procesar posteriormente en forma de varilla o alambre. De acuerdo con el estado de la técnica, se puede utilizar directamente un equipo de colada en continuo junto con un dispositivo de enrollamiento para procesar directamente la aleación madre en rollos de varilla o alambre. De forma alternativa, se pueden utilizar otros procedimientos de colada y conformado para obtener el afinador de grano en la forma y el tamaño deseados.The mother alloy obtained is cast by casting by means of the usual procedure in ingots ("waffles"), blocks or bars that can be subsequently processed in the form of a rod or wire. According to the state of the art, it can be used directly a continuous casting equipment together with a winding device to directly process the mother alloy in rod or wire rolls. Alternatively, other casting and shaping procedures can be used to obtain the grain tuner in the desired shape and size.
La aleación madre es apta para ser utilizada para el afino de grano de aluminio y de sus aleaciones. Se puede utilizar en forma de lingotes, barras o varilla según las técnicas de afino de grano.The mother alloy is suitable for use in the refining of aluminum grain and its alloys. It can be used in the form of ingots, bars or rod according to grain refining techniques.
Es importante destacar que la microestructura de la aleación madre obtenida mediante el procedimiento descrito contiene las tres fases siguientes:It is important to note that the microstructure of the mother alloy obtained by the described procedure contains the following three phases:
- Fase matriz, compuesta de α-Al . - Fase primaria intermetálica de aluminuro- Matrix phase, composed of α-Al. - Primary intermetallic aluminum phase
TiAl3.TiAl 3 .
- Fase ternaria de titanio-cinc-carburo. Además, en la microestructura se pueden encontrar algunas trazas de carbono libre. En resumen, en la aleación preconizada el contenido de titanio es como mínimo del 1% y como máximo del 20%, el contenido de carbono es como mínimo del 0,01% (100 ppm) y como máximo del 3% y el contenido de cinc es como mínimo del 1%. En un ejemplo de realización del afinador de grano objeto de la invención, en las Fig. 1 y 2 se presenta la micro estructura típica de una aleación Al- 6%Zn-3, 5%Ti-0, 4%C obtenida en forma de varilla.- Ternary phase of titanium-zinc-carbide. In addition, some traces of free carbon can be found in the microstructure. In summary, in the recommended alloy the titanium content is at least 1% and at most 20%, the carbon content is at least 0.01% (100 ppm) and at most 3% and the content of Zinc is at least 1%. In an exemplary embodiment of the grain tuner object of the invention, the typical microstructure of an Al-6% Zn-3, 5% Ti-0, 4% C alloy obtained in form is presented in Figs. 1 and 2 of rod.
Se llevaron a cabo, asimismo, ensayos de afino de grano TPl utilizando el nuevo afinador y se compararon los resultados con los obtenidos con afinadores de grano comerciales disponibles de Al-Ti-B y Al-Ti-C. En las Fig. 3, 4, 5 y 6 se incluyen las típicas macrografias de los ensayos TPl realizados. Puede verse que en el ensayo convencional corto de 2 min., llevado a cabo con aluminio comercial puro de 99,7%, con el nuevo afinador Al-6%Zn-3, 5%Ti- 0,4%C se obtuvo un tamaño de grano de 110 μm, que es ligeramente mas fino que el obtenido con Al-5%Ti-l%B (115 μm) y considerablemente mas fino que el obtenido con Al-3, 5%Ti-0,2%C (170 μm) .Likewise, TPl grain refining tests were carried out using the new tuner and the results were compared with those obtained with commercial grain tuners available from Al-Ti-B and Al-Ti-C. The typical macrographs of the TPl tests performed are included in Figs. 3, 4, 5 and 6. It can be seen that in the conventional trial 2 min short, carried out with 99.7% pure commercial aluminum, with the new Al-6% Zn-3, 5% T-0.4% C tuner, a grain size of 110 μm was obtained, which is slightly thinner than that obtained with Al-5% Ti-l% B (115 μm) and considerably finer than that obtained with Al-3, 5% Ti-0.2% C (170 μm).
