Effects of Raw Powder Morphology and Size on Tensile Properties of SPS-Consolidated TiB/Ti Composites

Abstract:

Titanium matrix composites (TMC) exhibit excellent specific strength and corrosion resistance. TiB whiskers can be formed in titanium by solid-state reaction between titanium and TiB2 powders. The formation of TiB whiskers results in the improvement of tensile strength, Young's modulus and Vickers hardness. In this study, TiB reinforced pulverized or gas atomized pure titaniums were fabricated by spark plasma sintering. We focus on the effects of the powder morphology and size on the tensile properties of TiB/Ti composites. We will investigate the sintering performance and microstructures of TiB/Ti composites.
