摘要
本文研究了Ti-8Al-1Mo-1V近α型钛合金的熔炼工艺,锻造工艺和热处理工艺。等轴组织具有良好的室、高温拉伸强度、塑性和适当的高温蠕变抗力,并具有优良的冲击韧性。双态组织和网蓝组织的综合性能则次之。但塑性和冲击韧性最差。
In this paper, the melting and heat treatment processes of a near α titunium alloy Ti-8Al-l Mo-1 Vhave been studied. The experiment result shows that equiaxed microstructure demonstrates good strength andductility at either room or elevated-temperature, as well as a moderate creep resistance and good toughness.The overall property of basket-weave and bimorphlogy microdructure is second to that of equiaxed mi-crostructure.Although the aligned microstructure exhibits the excellent creep resistance,it has very poor duc-tility and toughness.
