Effect of hydrogenation content on high temperature deformation behavior of Ti–6Al–4V alloy in isothermal compression
Isothermal compression of hydrogenated Ti–6Al–4V alloy was carried out on a Thermecmaster-Z simulator at deformation temperatures between 760 and 920 ∘ C , constant strain rate between 0.01 and 10.0 s - 1 , and a maximum height reduction of 60%. The high temperature deformation behavior of hydrogena...

, and a maximum height reduction of 60%. The high temperature deformation behavior of hydrogenated Ti–6Al–4V alloy was characterized based on an analysis of the stress–strain behavior, kinetics, and processing map. The smallest activation energy for deformation obtained in isothermal compression of hydrogenated Ti–6Al–4V alloy is 208.3
kJ/mol in the two-phase region of Ti–6Al–4V alloy with hydrogen contents of 0.2
wt%. Three unstable deformation regions were obtained by constructing the processing map of hydrogenated Ti–6Al–4V alloy with hydrogen contents of 0.2
wt%. |
