通过对TA18合金进行不同工艺的退火实验,得出去应力退火温度、保温时间对成品管材退火后力学性能的影响,并从理论上分析讨论了产生这种影响的原因。 By annealing the TA18 alloy in different process, the effects of annealing temperature and holding time on the mechanical properties of the finished pipe after annealing were obtained, and the reasons for the effect were also analyzed and discussed theoretically.
