两相钛合金热加工组织与织构演变的研究进展

Research Progress of Microstructure and Texture during Hot Working of α/β Titanium Alloys

两相钛合金的突出特点包括比强度高,高温性能好,抗腐蚀性能优异,因此,应用于其它金属不能满足的航空产品中。它在不同温度变形加工和热处理,所得的组织和织构差别很大,这对力学性能影响较大,因此探究钛合金的组织和变形织构演变机理具有理论指导意义和工程价值,且一直是国内外研究的热点。

With excellent characteristics of high strength,corrosion resistance and low density,the two-phase α/β titanium alloy was the backbone of aerospace applications.The mechanical behavior of α/β titanium alloy depended on the microstructure and texture developed during thermo-mechanical processing.So it was important to study the evolution of microstructure and texture for theory and practice,and no doubt the focus of domestic and foreign studies.
