Densification behaviour of titanium alloy powder under hot isostatic pressing

Densification behaviour of titanium alloy powder was investigated under hot isostatic pressing. Experimental data were obtained for titanium alloy powder at various pressures and temperatures during hot isostatic pressing. The densification model of Abouaf and co-workers under power law creep was implemented into a finite element analysis program (Abaqus) to compare with experimental data. The agreements between finite element calculations and experimental data for densification of titanium alloy powder were good during hot isostatic pressing. Finite element calculations for the shape change and density distribution of a sample were also compared with experimental data.
