Abstract

Blended elemental powder metallurgy using titanium hydride and Al–Fe–Cr master alloy powders was employed to produce a new Ti–1.5Al–1Fe–7.2Cr (wt.%) transition α + β/β metastable-type alloy. A simple process involving blending, cold pressing, and sintering resulted in a material with a residual porosity of not higher than 3.9–5%, a uniform and relatively fine-grained microstructure (average β-grain size of less than 100 μm), and acceptable mechanical properties. The influence of subsequent annealing and hot pressing on the microstructure evolution and porosity reduction was investigated. The results indicated that optimized regimes of hot deformation and heat treatment produced a structural state with a good combination of strength (UTS = 970 MPa) and ductility (El = 14.7%, RA = 35%).
