将二次真空自耗熔炼的Ti-55钛合金铸锭轧制成1.2 mm厚的薄板，研究Ti-55钛合金超塑性板材的显微组织与力学性能。结果表明，显微组织均匀，晶粒极细的Ti-55钛合金超塑性板材, 具有良好的室温拉伸性能和超塑性能。超塑性拉伸试验表明，在一定的变形温度范围(880~920 ℃)与变形速率(1.4×10−3 s−1)下，Ti-55钛合金板材超塑性伸长率可达到700%以上。
The 1.2 mm thick plates of Ti-55 alloy were rolled from ingots melted by twice vacuum arc furnaces. Microstructure and properties of superplastic plate of Ti-55 alloy were studied. The results show that very fine crystalline grain and good room temperature tensile property have obtained through improved rolling processing. With this processing, a total elongation above 700% could be obtained at 880−920 ℃ at strain rate of 1.4×10−3 s−1.
