Studies on Titanium Cenosphere Composite Developed by Powder Metallurgy Route

摘要

The present study concerns detailed microstructural investigation and property evaluation of titanium-cenosphere composite developed by powder metallurgy route. The main process variables for the development of titanium-cenosphere composite were cenosphere particle size, sintering time, and sintering temperature. Followed by sintering, a detailed characterization of the sintered parts in terms of density, microstructure, composition and phase has been carried out. The compressive strength of the sintered component has also been evaluated in details. The density of the sintered pellets varied with process parameters and is significantly reduced (2.5-2.11 g/cm~3) as compared to as-received titanium (4.5 g/cm~3). The compressive yield strength of the sintered pellet is reduced as compared to as-received Ti-6Al-4V.
