Abstract
Titanium aluminides have become promising materials for high-temperature applications, but the relatively poor oxidation resistance and elevated-temperature strength of these alloys limit their application to temperatures lower than 1000 °C. Niobium addition improves the properties of titanium aluminide. However, the mechanical, metallurgical, and corrosion properties of Ti-Al-Nb may be improved by treatment with a laser beam. Consequently, the present study examines the properties of Ti-15Al-20Nb alloy subjected to the Nd: YAG laser melting process. Hardness in the surface region increases to twice the base material hardness, and corrosion resistance improves considerably after laser treatment.
