Preparation of Ti3Al Based Alloy Expansion Part for Nozzle by Powder Metallurgy
Ti3Al based alloy has performed a comprehensive properties of low density, high tensile strength and excellent oxidation resistant at high temperature, which results in a good potential application in aerospace areas. In this paper, technologies relevant to preparation of Ti-23Al-17Nb expansion part for nozzle have been studied, and main properties of the part have been test and evaluated. The result revealed that Ti3Al based alloy prepared by powder metallurgy can replace nickel based alloy to be a candidate materials for high temperature structures.
