摘要

制备了一种基于 Ti-Al-Zr-Nb-V 的合金，并研究了其在高温下的变形行为。通过光学显微镜、扫描电子显微镜、热分析和机械测试对合金的微观结构和相进行了表征。结果表明，Ti-Al-Zr-Nb-V 合金在拉伸时，在 975℃ 至 1100℃ 范围内表现出超塑性效应，伸长率高达 400%。研究发现，超塑性发生在 α+β→β 转变的温度区域，并伴随着晶粒大小的变化和合金元素在相间的重新分布。

Study of titanium alloy Ti–Al–Zr–Nb–V during heating under deformation and its phase transformation features

An alloy based on Ti–Al–Zr–Nb–V was prepared and its deformation behavior at elevated temperatures was studied. The microstructure and phase of the alloys were characterized by optical microscopy, scanning electron microscopy, thermal analysis, and mechanical testing. The results showed that the Ti–Al–Zr–Nb–V alloy, when stretched, exhibits a superplasticity effect in the range of 975℃ to 1100℃, with an elongation of up to 400%. It was found that superplasticity develops in the temperature region of the α+β→β transition and is accompanied by a change in grain size and redistribution of alloying elements among phases.
