锻造工艺对TC10钛合金棒材性能的影响

Effects of forging technics on performance of TC10 titanium alloy stick

对锻造工艺主要参数,如坯料加热温度、锻比和变形方式,对锻棒性能的影响进行研究。小型试验结果表明:当成品火次前,坯料的加热温度控制在比相变点低20～30℃,锻比应大于4时,棒材具有良好的室温拉伸性能,可完全满足国标GB/T2965—2007要求。

The effects of forging technic parameters, such as heat up temperature of preform body, forging ratio and distortion manner, on the stick performance were studied. The experimental results show that the heating temperature of finished pormer preform body should be controlled to be lower 20-30 ℃ than transformation point, and the forging ratio should be larger than 4, then the stick has good extend performance at room temperature, satisfying the demand of Chinese Standard GB/T2965--2007.
