关键词: Dilatometry, Sintering, Diffusion, Activati

Abstract: The effect of Al addition (2 and 5 at. pct) on sintering kinetics of Ti power was investigated. Al reduces the sintering rates, sinter density, increases activation energy of sintering and accelerates the grain growth. Sintering was controlled by mixed mode, i.e. transient liquid phase sintering, formation of intermetallics, and Ti grain boundary diffusion in TiAl2 and other intermetallics.

Key words: Dilatometry, Sintering, Diffusion, Activation energy
