TA7-d钛合金是低间隙元素含量(其中O_2<0.12%)的α型钛合金。其名义成份为Ti-5Al-2.5Sn。室温下具有中等强度,可焊性能好,低温塑性高。它是一种在超低温下使用的优良结构材料。本试验研究了TA7-d钛合金显微组织形貌对低温性能的
TA7-d titanium alloy is a low-gap element content (O_2 <0.12%) α-type titanium alloy. The nominal composition of Ti-5Al-2.5Sn. Medium strength at room temperature, good solderability, high plasticity at low temperatures. It is an excellent structural material for use at cryogenic temperatures. This study investigated the TA7-d titanium alloy microstructure morphology of the low temperature performance
