Abstract

The effect of cholrine content on the tensile properties of titanium aluminide (TiAl) have been studied on the specimens which are made by self-propagating high-temperature synthesis (SHS) using three kinds of titanium raw powder. Chlorine as an impurity was found to enhance the formation of porosities, resulting in degrading the mechanical properties, especially the tensile strength.
