Rapid consolidation of nanostructured Ti from mechanically activated Ti and TiH(2) by pulsed-current activated sintering, and the mechanical properties of the product

摘要

Dense nanostructured Ti was sintered from mechanically activated Ti and TiH(2) powders by pulsed-current activated heating under a pressure of 80 Mpa. TiH(2) powder was decomposed to Ti during sintering. The hardness of the Ti increased, and the average grain size of the Ti decreased, with increasing milling time.
