Dilatometric Sintering of Ti-2Al and Ti-5Al Elemental Powder
Dilatometric Sintering of Ti-2Al and Ti-5Al Elemental Powders

The effect of Al addition (2 and 5 at. pct) on sintering kinetics of Ti power were 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.
