Abstract
Description
Изобретение относится к области металлургии, в частности к разработке сплава на основе титана, используемого для применения в качестве высокопрочного конструкционного материала, подвергающегося упрочняющей термической обработке при ступенчатом отжиге. The invention relates to the field of metallurgy, in particular to the development of an alloy based on titanium, used for use as a high-strength structural material subjected to hardening heat treatment during step annealing.
Наиболее близким по технической сущности и достигаемому результату к предложенному сплаву является известный сплав на основе титана, содержащий компоненты в следующем соотношении, мас.%:
Алюминий - 2 - 4
Ванадий - 14 - 20
Хром - 2 - 5
Олово - 2 - 4
Молибден - 0,5 - 3,0
Цирконий - 0,3 - 2,0
Ниобий - 0,01 - 0,40
Титан - Остальное [1]
Недостатком известного сплава является низкая пластичность в холодном состоянии, связанная с ростом микро- и макрозерна при производстве полуфабрикатов путем горячего деформирования.The closest in technical essence and the achieved result to the proposed alloy is a known alloy based on titanium containing components in the following ratio, wt.%:
Aluminum - 2 - 4
Vanadium - 14 - 20
Chrome - 2 - 5
Tin - 2 - 4
Molybdenum - 0.5 - 3.0
Zirconium - 0.3 - 2.0
Niobium - 0.01 - 0.40
Titanium - Else [1]
A disadvantage of the known alloy is the low ductility in the cold state associated with the growth of micro and macro grains in the production of semi-finished products by hot deformation.
Задачей изобретения является создание высокопластичного и высокопрочного титанового сплава, допускающего интенсивную холодную деформацию (более 70%) при массовом производстве деталей и конструкций (болты, винты, трубы, листы, лента и проч.). The objective of the invention is the creation of a highly plastic and high-strength titanium alloy that allows intense cold deformation (more than 70%) in the mass production of parts and structures (bolts, screws, pipes, sheets, tape, etc.).
Поставленная задача достигается тем, что сплав на основе титана, содержащий алюминий, ванадий, хром, олово, молибден, дополнительно содержит железо и бор в следующем соотношении компонентов, мас.%:
Алюминий - 2 - 4
Ванадий - 14 - 20
Хром - 2 - 4
Олово - 2 - 4
Молибден - 0,5 - 3,0
Железо - 1 - 2,5
Бор - 0,005 - 0,020
Титан - Остальное
Легирование небольшим количеством бора сильно измельчает при обязательном содержании 1,0 - 2,5% железа микро- и макрозерно и повышает тем самым пластичность и прочность полуфабрикатов из данного сплава.The problem is achieved in that the titanium-based alloy containing aluminum, vanadium, chromium, tin, molybdenum, additionally contains iron and boron in the following ratio of components, wt.%:
Aluminum - 2 - 4
Vanadium - 14 - 20
Chrome - 2 - 4
Tin - 2 - 4
Molybdenum - 0.5 - 3.0
Iron - 1 - 2.5
Boron - 0.005 - 0.020
Titanium - Else
Doping with a small amount of boron strongly crushes the micro- and macrograin with an obligatory content of 1.0 - 2.5% iron and thereby increases the ductility and strength of semi-finished products from this alloy.
Изобретение иллюстрируется следующими примерами. Составы предложенного и известного [2] сплава, приведенные в табл. 1, выплавляли в вакуумно-дуговых печах в два переплава. Допустимое содержание в предложенном сплаве неизбежных примесей следующее, мас.%: кремний до 0,3, кислород до 0,15, углерод до 0,1, азот до 0,05, водород до 0,02. После деформирования и термообработки из заготовок (пруток) изготавливали образцы для проведения механических испытаний. The invention is illustrated by the following examples. The compositions of the proposed and known [2] alloy are given in table. 1, smelted in vacuum arc furnaces in two remelting. The permissible content of the proposed alloy of inevitable impurities is as follows, wt.%: Silicon up to 0.3, oxygen up to 0.15, carbon up to 0.1, nitrogen up to 0.05, hydrogen up to 0.02. After deformation and heat treatment, samples were prepared from billets (bar) for mechanical testing.
Предел прочности, предел текучести, относительное сужение и относительное удлинение определялись по ГОСТ 1497-84. Испытание на осадку проводилось по ГОСТ 8817-82. Tensile strength, yield strength, relative narrowing and elongation were determined according to GOST 1497-84. Draft test was carried out according to GOST 8817-82.
Термическая обработка предложенного сплава включает ступенчатый отжиг в вакуумных печах или в печах с защитной атмосферой по режиму: нагрев до 780oC, выдержка 1 ч, охлаждение с печью до 480-520oC, выдержка 4-8 ч, охлаждение с печью. Технологическая пластичность при испытании на осадку определялась после отжига в печах с защитной атмосферой по режиму: 780oC, 1 ч, охлаждение с печью.Heat treatment of the proposed alloy includes step annealing in vacuum furnaces or in furnaces with a protective atmosphere according to the regime: heating to 780 ° C, holding for 1 hour, cooling with the furnace to 480-520 ° C, holding for 4-8 hours, cooling with the furnace. Technological plasticity during the sludge test was determined after annealing in furnaces with a protective atmosphere according to the regime: 780 o C, 1 h, cooling with the furnace.
Как видно из табл. 2, предложенный сплав в термоупрочненном состоянии обладает более высокой прочностью (в среднем более 100 МПа) и особенно важно, что характеристики пластичности также повышаются (относительное сужение и относительное удлинение в среднем в 1,5 раза). As can be seen from the table. 2, the proposed alloy in a heat-strengthened state has higher strength (on average more than 100 MPa) and it is especially important that the ductility characteristics also increase (relative narrowing and elongation by an average of 1.5 times).
Результаты испытаний на осадку у предложенного сплава выше в среднем на 30%. The test results for the sediment of the proposed alloy above an average of 30%.
Детали и конструкции, изготовленные из предложенного сплава, могут упрочняться без переноса в закалочную среду, т.е. в аргоновакуумных печах (см. табл. 2). Parts and structures made of the proposed alloy can be hardened without transfer to the quenching medium, i.e. in argon vacuum furnaces (see table. 2).
