Ti一6Al一4V(TC_4)合金是一种国外已被广泛应用的合金,为了适应工业发展的需要,解决生产中存在和发现的问题,稳定、提高产品质量,我们在621所、上海钢研所等单位协作下,对该合金在熔炼方面作了如下试验工作: (1)通过选择不同成份和颗粒大小的Al—V中间合金,探索引起合金锭和成品中主量元素铝、钒偏析及其金属夹杂的产生原因。(2)在冶标规定范围内调整铝、钒含量,以获得较好机械性能的成份配比。 Ti-6Al a 4V (TC_4) alloy is a foreign country has been widely used alloy, in order to meet the needs of industrial development, to solve the problems found in the production and stability, improve product quality, we in 621, Shanghai Steel Research (1) Through the selection of different composition and particle size of Al-V master alloy, to explore the alloy ingots and finished products in the main elements of aluminum, vanadium segregation and Its metal inclusions cause. (2) adjust the content of aluminum and vanadium in the range specified by the standard, in order to obtain better mechanical properties of the ingredients ratio.
