Claim 2:
3. The preparation process of the multi-component spherical alloy powder according to claim 1, characterized in that hot pressed sintering in step 4.3 includes three stages, which are:
(1) heating stage: putting the ball-milled powder into the graphite mold, then vacuumizing the furnace cavity, and increasing the temperature evenly to the sintering temperature;
(2) heat preservation stage: performing heat preservation at a set hot pressing temperature so that the element powder particles can be metallurgically bonded; and
(3) cooling stage: cooling the sample with the furnace after the heat preservation is completed.
