The Ti-Fe alloys are quite important among various Ti-based alloys doped with b-stabilisers. Severe plastic deformation by the high pressure torsion (HPT) leads to the strong grain refinement in Ti-Fe alloys. The high-pressure omega Ti-phase appears during HPTof the Ti-1 wt.% Fe alloy. However, the vTi does not appear after uniaxial compression at the same pressure, without torsion. vTi remains quenched after pressure release and disappears by heating around 140-150 degrees C. However, the further alloying with iron suppresses the formation of omega Ti-phase. As a result, vTi does not appear after HPTin the Ti-10 wt.% Fe alloy.
