研究兩種熱加工工藝對BTi-6431S高溫鈦合金厚板顯微組織和力學性能的影響。
熱加工工藝對BTi-6431S鈦合金厚板組織與性能的影響Effect of hot working process on microstructure and properties of BTi-6431S titanium alloy plate研究兩種熱加工工藝對BTi-6431S高溫鈦合金厚板顯微組織和力學性能的影響。結果表明，(α+β)軋制的厚板組織類型為類似于等軸的兩相區(qū)加工組織，β軋制的該合金厚板的顯微組織為典型的細片狀魏氏組織，該組織厚板的室溫和高溫強度明顯高于α+β軋制厚板的，而塑性稍低；該合金厚板在650 ℃時具有較高的高溫瞬時強度，可用于宇航工業(yè)650 ℃短時用結構件的制作。
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.
