摘要
分别用压力机热挤压法和两辊斜轧穿孔法获得钛及钛合金管坯,对比分析了两种不同方法制备的TA2,TA18,TC4管坯的显微组织和室温力学性能的差异。结果表明:管坯的力学性能受加热温度、变形量等因素影响,挤压管坯的组织均匀细小而斜轧穿孔的组织粗大,挤压工艺优于斜轧穿孔工艺。
Three kinds of titanium and titanium alloy TA2, TA18, TC4 tube blanks manufactured by hot extrusion and two-roll rotary piercing were studied. Their microstructures and properties are also investigated. The results show that hot extrusion is better than two-roll rotary piercing, properties and microstructures of tube blanks are affected by deformation temperature and strain rates, and the former is better than the later.
