Abstract
The present disclosure relates to a preparation process of a Ti3AlC2 ceramic phase-toughened molybdenum alloy. The preparation process includes: mixing MoO2 and Ti3AlC2 powders, sieving to obtain a mixed powder, and then conducting high-temperature hydrogen reduction; mixing a resulting reduced powder with a coarse-grained Mo powder to obtain a precursor powder; putting the precursor powder into a cladding material to allow hot-pressed sintering; subjecting an obtained sintered molybdenum alloy to high-temperature treatment and thermoplastic processing in sequence; and annealing an obtained processed molybdenum alloy to obtain a high-strength and high-toughness molybdenum alloy. In the present disclosure, a Ti3AlC2-containing ultrafine powder prepared by reduction is mixed with the commercial coarse-grained molybdenum powder in a certain proportion to obtain the precursor powder. After the precursor powder is subjected to the hot-pressed sintering, the molybdenum alloy can achieve a higher density and finer grains.
