Influence of processing parameters on microstructure and tensile properties of TG6 titanium alloy

▶ This paper highlights the relationships among processing parameters, microstructure and tensile properties of TG6 high temperature titanium alloy. ▶ The microstructural evolutions under different processing parameters were studied by the quantitative metallography, and the effects of microstructure on room and high temperature tensile properties of TG6 alloy were analysed by SEM and TEM. ▶ Linear relationships of elongation vs. volume fraction of primary α phase and ultimate tensile strength vs. thickness of lamellar α phase were determined.
