Manipulation of microstructure and mechanical properties during dehydrogenation of hydrogen-sintered Ti–6Al–4V

Ti–6Al–4V parts produced using the powder metallurgy process known as hydrogen sintering and phase transformation (HSPT) have been shown to exhibit superior mechanical properties than those produced using traditional titanium powder metallurgy techniques. In this work, the dehydrogenation step of HSPT is investigated as an additional method to further manipulate the microstructure of Ti–6Al–4V. By varying the dehydrogenation temperature, several...
