Abstract

Abstract

The thermal simulation test was carried out and high temperature deformation behavior of the as-cast Ti-6Al-4Sn-8Zr-0.8Mo-1.5Nb-1W-0.25Si short-time high temperature titanium alloy was studied. The experimental results show that the deformation of Ti-6Al-4Sn-8Zr-0.8Mo-1.5Nb-1W-0.25Si alloy is sensitive to the deformation temperature and deformation rate, and the true stress decreases significantly with the decrease of strain rate and the increase of deformation temperature. The hot working diagram was plotted using the high temperature compression stress-strain data. The analysis results demonstrate that 900-960 ℃, 0.035-0.368 s⁻¹ and 960-1 010 ℃, 0.165-0.577 s⁻¹ in the (α+β) phase region as well as 1010-1020 ℃, 0.165-1 s⁻¹ of β phase region are the most suitable regions for hot processing. The thermal deformation activation energy of (α+β) two-phase region is calculated to be 316.229 kJ/mol, and the constitutive equation of the region is established as well.
