چکیده انگلیسی
The microstructure evolution and phase composition of an α + β titanium alloy, Ti-3Al-5Mo-4.5V (wt.%), have been investigated. Electron probe micro analysis (EPMA) quantitative results manifest that the stability of β phase decreases with increasing quenching temperature, which is influenced by the significant variation of β-stabilizing elements concentration. Detailed microstructure analysis shows that the β âÂ Ï phase transformation does occur when quenching at 750 °C and 800 °C. The Ï-reflections change from incommensurate Ï-spots (750 °C) to ideal Ï-spots (800 °C) as the β stability of the alloy decreases. Further the decrease of β phase stability encourages the formation of athermal αâ²â² martensite, which has the following orientation relationships: [111]β//[110]αâ²â², [100]β//[100]αâ²â² and [-110]β//[00-1]αâ²â² with respect to the β matrix.
