Abstract:This study investigates the consolidation of pre-alloyed Ti–6Al–4V powder through thermomechanical processing that involves cold isostatic pressing, sintering, hot pressing and extrusion. The microstructural evolution, oxygen pick-up and tensile properties attained after each major consolidation step reveal that there was a significant oxygen pick-up during de-binding/sintering, hot pressing had improved strength/ductility by eliminating porosity and extrusion resulted in a relatively fine lamellar structure. … Show more
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.
