Abstract

Isothermal compression of the hydrogenated Ti-6Al-4V titanium alloy was carried out on a Thermecmaster-Z simulator at the deformation temperatures ranging from 760 to 920 °C, strain rate ranging from 0.01 to 10.0 s^-1 and a maximum height reduction of 60%. Processing maps in isothermal compression of the Ti-6Al-4V titanium alloy with different hydrogen contents are constructed. Efficiency of power dissipation and unstable regions has been obtained by calculating experimental data and by constructing processing maps of the isothermally compressed Ti-6Al-4V titanium alloy. Unstable regions in processing maps of the Ti-6Al-4V titanium alloy varies with hydrogen content resulting from the effect of hydrogen content on volume fraction and grain size of prior α phase in isothermal compression of the Ti-6Al-4V titanium alloy.
