摘要
研究了粉末冶金和压力加工方法制取的０．６ｍｍＭｏＬａ丝退火前后的显微组织、抗拉强度、延伸率、弯折次数等，并与同规格Ｍｏ１丝进行了对比．结果表明：ＭｏＬａ丝的再结晶温度达１８００℃，比Ｍｏ１丝高６００℃以上，完全再结晶后形成燕尾搭接状组织．经高温退火和再结晶退火后其抗拉强度、塑性。
Microstructures, tensile strength, elongation and flexibility before and after annealing have been studied for 06 mm diameter MoLa wire made by powder metallurgy and pressure working, as compared with the same size of Mo1 wire. The results show that the recrystalling temperature of MoLa wire is 1 800, which is 600 higher than that of Mo1 wire. After complete recrystallization, MoLa wire has an interlocking grain structure. The tensile strength, plasticity and tonghness of MoLa wire is higher than those of Mo1 wire after high temperature annealing and/or recrystallization annealing.
