(J11)Mechanical behavior and microstructure of a severe plastic deformation processed Ti-6Al-4Nb and Ti-10Al-4Nb alloys

摘要

Near α titanium alloys are important materials for aerospace applications, especially in hightemperature applications such as jet engine. Mechanical properties of Ti alloys strongly depend on theirprocessing route, then it is very important to understand microstructure change by different processing. In ourprevious study, Nb was found to improve oxidation resistance of Ti alloys. In this study, microstructure evolutionand mechanical properties of Ti-Al-Nb alloys were investigated after compression test in hot workingtemperatures in the α and β region.
