摘要

本文研究了一种圆形截面的热挤压钛合金（Ti6Al4V）。采用单轴拉伸试验对合金在不同温度和应变速率下进行变形。随后，利用电子背散射衍射技术对合金的微观组织进行了全面的分析。研究表明，在变形过程中形成的硬取向区域对合金的延展性有不利影响。该研究还强调了在不同温度下硬取向演变的原因。

Dynamic evolution of hard orientations and consequent ductility loss during uniaxial tension of Ti6Al4V alloy

This study was performed on a hot extruded titanium alloy (Ti6Al4V) of circular cross-section. The alloy was deformed at different temperatures and strain rates using the uniaxial tension test. Subsequently, a comprehensive microstructure analysis using an electron back-scattered diffraction technique was performed to investigate the microstructure of the alloy. The study revealed the formation of hard-orientated regions during deformation that adversely affected the ductility of the alloy. This study also highlights the reasons responsible for the evolution of hard orientations at different temperatures.
