Evaluation of different routes for HDH processing of Ti-6Al-4V alloy
An alternative route to the conventional hydriding and dehydriding process applied to Ti grade 5 (Ti-6Al-4V) were evaluated considering that dehydriding and sintering were carried out in a single step. Microstructure evolution, hydriding degree, chemical composition and shrinkage during sintering were investigated. High hydriding degree was obtained. A shrinkage higher than 15% was observed, and a sintered density 95% of the theoretical was obtained in spite of coarse milled hydride particles were used.
