Severe plastic deformation induced precipitation of the ordered α2-Ti3Al phase in Ti–5Al–2Sn–2Zr–4Mo–4Cr

The typical two-phase titanium alloy of Ti–5Al–2Sn–2Zr–4Mo–4Cr was subjected to severe plastic deformation (SPD) by using high energy shot peening (HESP) at room temperature. Here, we experimentally investigated the SPD-induced atomic diffusion and phase transformation in the HESP processed Ti–5Al–2...
