| Summary: | This research is focused on intermetallic TiAl and their oxidation behavior for structural materials at high temperatures in automotive, aerospace and gas turbine
industries. However, the commercial application of Ti-Al is currently limited by their insufficient oxidation resistance at temperature above 700-850oC. The addition of
alloying elements such as Nb, Cr and W is significant in producing good Ti-Al alloys for high temperature applications. Ti-Al alloys were fabricated using arc- melting furnace. Then the phases present, microstructure evaluation and hardness test were characterized using XRD, FESEM/EDX and Vikers hardness.
