Abstract

The densification kinetics of a blend of unalloyed Ti and Al-40V master alloy powders are measured during uniaxial hot pressing under 3-10 MPa pressure for thermal cycling (860-1020 °C) or isothermal (1020 °C) conditions. Subsequent heat treatment for 4-16 h at 1020 °C results in a homogeneous Ti-6Al-4V microstructure. This process provides a low-cost alternative to hot isostatic pressing of prealloyed Ti-6Al-4V powders.
