Abstract
Powder metallurgy based on cold isostatic pressing, vacuum sintering and hot isostatic pressing (HIP) reveals the possibilities of mass producing critical parts in near net shape. The multi-stage process consists of: (i) cold isostatic compaction to a green preform; (ii) supersolidus vacuum sintering of compact to more than 90% density; and (iii) final consolidation via hot isostatic pressing to densify the preform. Three-point flexural tests were carried out on the sintered and HIPped specimens. Microstructure and porosity evaluations were conducted using scanning electron microscopy and image analysis. © 1997 Published by Elsevier Science S.A.
