Nanosized TiCu powders were synthesized by high energy ball milling of micron-sized Ti and Cu powders. Dense TiCu could be consolidated by high frequency induction sintering method within 1 min using both horizontally milled elemental powders of Ti+Cu and mechanically synthesized powders of TiCu. The consolidation was accomplished under the combined effect of induced current and applied mechanical pressure. The grain size, sintering behavior and hardness of TiCu sintered from both powders were examined.
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.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
