ABSTRACT:
A method consisting of a high temperature diffusion treatment, preferably preceded by a hot isostatic pressing treatment, by which the deleterious effects of hard alpha defects may be substantially reduced or eliminated from ingots of titanium or titanium alloys without adversely affecting the subsequent structure and properties of ingots processed by the method and the homogenized, substantially hard alpha and inclusion-free ingots produced thereby.
