Definitions

the invention relates to a process for producing monotectic alloys with a comparatively large mixture gap in the liquid state and, after solidification, a minority phase present in droplet form and having a greater density than the matrix itself, by continuous casting of a melt heated to a temperature above the separation temperature high pouring and cooling speed.
a sufficiently uniform dispersion of the droplets in the matrix can therefore only be obtained with relatively low contents of the dispersed phase and / or by extremely rapid cooling.
Z. Russ. Met. 1979 (1), pp. 88-93 (in English) provided aluminum alloys with up to 33% lead or up to 10% bismuth at 200 to 250 ° C above the solidus isotherms and 150 to 200 ° C above the Heat segregation isotherms and the droplets of atomized under the action of centrifugal force Spray the melt in less than 0.1 s in water, whereby a cooling rate of 103 to 104 K / s is achieved.
the minority phase is finely dispersed in the droplets.
GB-A-2 182 876 describes a strip casting process for the production of binary alloys, for example aluminum lead alloys, copper lead alloys and copper indium alloys, in which the alloy which is completely dissolved in the molten state has a cooling rate of 105 to 106 K / s is poured. In this way, a uniform dispersion of the fine-grained lead or indium particles in the aluminum or copper matrix is achieved. With this method, only very thin cast strips with a thickness of ⁇ 1.0 mm can be produced, which are, however, not suitable for further processing, for example by plating on steel.
US-A-4 198 232 is concerned with the manufacture of a monotectic alloy by doping molten aluminum or zinc alloys containing bismuth and lead with a transition metal, preferably iron, to destroy and inject the liquid-solid intermediate layer of the system Form cell structure with directional solidification at given temperature gradients and low solidification speed.
a transition metal preferably iron
a molten aluminum bearing alloy with 4% by weight of lead which may possibly contain up to a total of 10% of other components, is applied to the water-cooled surface in a layer thickness of 1 to 5 mm of the steel strip of a rotary belt casting machine, so that the melt, which is at a temperature of more than 900 ° C., is cooled to a solidification temperature of approximately 650 ° C. in less than 0.1 s.
lead particles with a size of 50 ⁇ m should be evenly distributed in the aluminum matrix. Due to technical difficulties, especially with the Cooling the cast belt, this method has not found its way into practice. With strip thicknesses of> 1 mm, sedimentation and coagulation of the minority phase cannot be sufficiently avoided.
the melt is cast vertically into a strip or wire of 5 to 20 mm in thickness or diameter.
the withdrawal direction of the strand thus coincides with the direction of gravity sedimentation of the heavier minority phase. If the cooling and solidification speed is sufficiently high, a very steep temperature gradient is maintained in front of the solid / liquid phase boundary, so that the distance between the separation and solidus isotherms within the system and thus the sedimentation distance is as short as possible.
the temperature or path interval for the sedimentation of the droplets of the minority phase is given by the isotherms of the segregation temperature and the temperature of the monotectic reaction at which the matrix phase solidifies and thereby includes the second still liquid phase in the distribution then present.
the dispersed droplets in the minority phase are subject to Marangoni convection, that of Stokes sedimentation counteracts. Since the Marangoni convection takes place in the direction of the temperature gradient and the cooling only acts from the surface of the belt, the Marangoni convection is partly directed inwards in the areas of the belt near the surface, so that in the areas near the surface there is a depletion of the minority phase. which advantageously increases the stability of the edge shell and facilitates subsequent processing steps such as forming, plating or heat treatment.
the alloy melt is cast at a constant speed of 10 to 30 mm / s, preferably 15 to 25 mm / s, the cooling rate being 300 to 1500 K / s, preferably 500 to, according to a further feature of the invention 1000 K / s.
the method according to the invention is particularly suitable for the production of slide bearing materials made of aluminum alloys, which contain one or more of the components 1 to 50% by weight, preferably 5 to 30% by weight of lead, 3 to 50% by weight, preferably 5 to 30% by weight.
suitable zinc alloys with one or both of the components 1 to 30% by weight, preferably 5 to 20% by weight bismuth and 1 to 30% by weight lead, and additionally containing one or both of the components can be used as slide bearing materials Produce 0.001 to 50 wt .-%, preferably 0.001 to 0.2 wt .-% or 6 to 50 wt .-% aluminum and 0.1 to 5 wt .-% copper.
the method according to the invention can also be used to produce copper alloys with 1 to 60% by weight, preferably 12 to 50% by weight, lead.
the method according to the invention is also suitable for producing alloys which can be used as materials for special electrical conductors and for electrical contacts.
a device in which the melt template is directly supplied with a strongly cooled, vertically arranged mold via a pouring nozzle made of ceramic material with a reduced cross section compared to the casting format, which, following a short metallic cooling surface, acts on the casting strand is provided by water.
a casting device constructed in this way ensures a uniform melt flow within the entire casting strand.
the thermal separation between the hot feed system and the short mold followed by secondary water cooling allows the strand to be strongly cooled, resulting in a very large temperature gradient in front of the solidification front and one rapid growth of the solidified strand shell directly behind the pouring nozzle.
An aluminum alloy melt with 5% bismuth and 5% silicon and a temperature of> 1000 ° C is cast at a speed of 800 mm / min. Due to the arrangement of the melt supply (1), the pouring nozzle (2) and the mold (3) with the cooling water supply (4) for the mold cooling before the start of casting and the cooling water supply (5) to the cooling grooves (6) for the direct cooling of the strip ( 7) a temperature gradient before the solidification front of 500 K / cm and a cooling rate of a certain melt volume of about 700 K / s are achieved.
the structure of the 10 mm thick cast strip is sufficiently uniform over the entire strip length, as shown in FIG. 2. The marginal areas depleted as a result of the Marangoni convection on the minority phase are clearly recognizable.
