Influence of heat treatment on microstructure and mechanical properties of titanium alloy grade TI6AL4V

摘要

In this work, the effect of heat treatment on the control of the volume share of a phase in a two-phase titanium alloy α + β from the Ti6Al4V grade was analyzed. The applied heat treatments resulted in obtaining a volume share of alpha phase in the range of 60% to 96%. The highest hardness was obtained with a sample share 88% a phase, which was characterized by a microstructure consisting of grains of a phase and β phase regions of the phase precipitates of α'.
