热加工工艺对BTi-6431S钛合金厚板组织与性能的影响Effect of hot working process on microstructure and properties of BTi-6431S titanium alloy plate
研究两种热加工工艺对BTi-6431S高温钛合金厚板显微组织和力学性能的影响。结果表明，(α+β)轧制的厚板组织类型为类似于等轴的两相区加工组织，β轧制的该合金厚板的显微组织为典型的细片状魏氏组织，该组织厚板的室温和高温强度明显高于α+β轧制厚板的，而塑性稍低；该合金厚板在650 ℃时具有较高的高温瞬时强度，可用于宇航工业650 ℃短时用结构件的制作。
The effects of two hot working processes on microstructure and properties of BTi-6431S high temperature titanium alloy plate were studied. The results show that the microstructure of plate in α+β rolling is similar to equiaxed two-phase working microstructure, and the microstructure in β rolling is typical fine lamellar Widmannstaetten structure. The strengths in β rolling at room temperature and high temperature are obviously higher than those in α+β rolling, while the ductility of plate in β rolling is slightly lower. The plates have higher high-temperature transient strength at 650 ℃ and can be used to make short time structure components at 650 ℃ for aerospace industry.
