Intermetallic materials based on titanium aluminides have attracted wide-spread attention for potential use in high temperature applications because of their outstanding properties including high specific strength, good creep and corrosion resistance. However their applications have been limited by low ductility, so that generally hot working can only be accomplished at temperatures above 1000-1200oC. A reduction in the temperature range in which the alloys are superplastic would be commercially attractive. This can be achieved through microstructure refinement to a submicron grain size.
