TC11钛合金应力热稳定性和非应力热稳定性研究

A Study on Stress Pyrolytic Stability and Non-stress Pyrolytic Stabiylty of TC11 Ti-Alloy

本文是用 TC11钛合金经常规锻、近β锻和正β锻等三种工艺处理后,对其组织性能,应力热稳定性和非应力热稳定性进行了研究,给出了 TC11钛合金获得良好热稳定性的工艺。

In this paper,the microstructure properties,stress and non-str- ess pyrolytic stability of TCll Ti-alloy have been investgated after deformation at the temprature of lower β transiton,lower β transtion a little and higher β transtion a little.It gave out the tenques that could win a good pyrolytic stability of TCll Ti-alloy.
