[J14] Hardening and embrittlement in Ti-10Mo air-cooled after annealing

*Xiuqun Wang1, Yan Chong1, Nobuhiro Tsuji1 (1. Department of Materials Science & Engineering, Graduate school of Engineering, Kyoto University)

Keywords:Metastable β titanium alloy、TRIP/ TWIP、Hardening、Embrittlement

This work achieves ultrahigh yield strength in air-cooled Ti-10Mo alloy, accompanied by ductility loss. The hardening and embrittlement mechanisms are discussed by considering α and ω phase.
