A low cost metastable beta titanium alloy: Thermal treatments, microstructures and mechanical properties

摘要

This paper presents the first results of an ongoing research which was set up to investigate the influence of ω phase on the deformation mechanisms of LCB Ti (Ti-6,8Mo-4,5Fe-1,5Al). Depending of thermal treatment, ω phase precipitation has been investigated by resistometric measurements and TEM observations. Then differences in the mechanical behaviour have been investigated (in connection with the starting microstructure) from textural evolution data during cold rolling.
