TiAl based intermetallics are considered as potential high-temperature structural materials due to their attractive properties at high temperatures. Previous studies of the mechanical behavior of single phase and dual phase TiAl alloys revealed that these types of alloys have good ductility at high temperatures, but poor ductility at ambient and lower temperatures. Recently some triple phase TiAl alloys were developed by the addition of [beta] stabilizing elements, and the [beta] phase was found not to improve the room temperature ductility. However, few reports have been made about the high temperature behavior of the triple phase TiAl alloys. This research is concentrated on the temperature dependence of the mechanical properties of a triple phase Ti-Al-Cr alloy.
