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. |
