摘要

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.
