Extensive research over the past two decades has led to the development of alloys such as Ti-46.5Al-3Nb-2Cr-0.2W ({gamma}-TiAl) and Ti-25Al-10Nb-3V-1Mo (super {alpha}{sup 2}-Ti{sub 3}Al), which offer a good balance of formability and high temperature strength. Although the mechanical behavior of these intermetallic alloys at low strain rates has been extensively studied, fewer studies have probed the systematic mechanical behavior of these alloys over a wide range of strain rates and temperatures. The purpose of this study is to compare and contrast the behavior of these two intermetallic alloys over a wide range of strain rates and temperatures. Variations in the mechanical responses of these two structurally different Ti-Al based intermetallics are documented.
