Gamma titanium-aluminide (y-TiAl) based alloys are potentially suitable as advanced structural materials for high performance applications such as components in aerospace vehicles, aircraft turbine, and automotive engines due to their unique and superior properties at high temperatures. Hot pressing combined with mechanical alloying (MA) has been reported as favorably as fabrication route to produce various alloys from elemental powders since they offer high densification, particularly for consolidation of reactive elements, as well as elements with significantly different melting points. In this study, formation and densification behavior of y-TiAI alloys was investigated using mechanical alloying and hot pressing at temperatures ranging from 950-110° DC.
