Abstract
A preparation method of a reticular Ti5Si3 and dispersed TiC enhanced TiAl-based composite relates to the preparation method of the TiAl-based composite. The invention aims to solve the problems that the oxidation resistance of the TiAl alloy is poor above 800 DEG C and the preparation process of the high density TiAl alloy is complicated. The method comprises the following steps: 1) preparing the mixed powder of Ti and SiC; 2) performing pressure infiltration in a vacuum hot press sintering furnace; and 3) preparing the reticular Ti5Si3 and dispersed TiC enhanced TiAl-based composite. The method adopts the reaction pressure infiltration technology to obtain the high density material and increase the oxidation resistance of the TiAl alloy, thus the high-temperature application requirement under 900 DEG C can be met, the density of the material can be effectively increased and the method is especially suitable for the preparation field of the TiAl alloy.
