Ti-Al BASE ALLOY CONTAINING MISCH METAL

The present invention relates to a titanium-aluminum based alloy. The present invention provides a titanium-aluminum based alloy added with a misch metal, comprising : 42-48 at% of aluminum (Al); 1-5 at% of molybdenum (Mo); 0.1-4 at% of niobium (Nb); 0.01-1.5 at% of misch metal; and the remaining portion including titanium (Ti) and inevitable impurities. According to one embodiment of the present invention, the size of a crystal of the alloy is miniaturized, and normal temperature ductility, high temperature creep characteristics, and oxidation resistance of the alloy can be improved.COPYRIGHT KIPO 2018
