Detailed Description
The present invention will be further described with reference to the following examples and the accompanying drawings.

firstly, cleaning a ball milling tank made of alloy materials, then loading high-hardness grinding balls and n-heptane, putting the ball milling tank into a three-dimensional vibration ball mill for hollow milling for 5-10 minutes, then taking out the ball milling tank, and cleaning again. A high hardness grinding ball refers to a grinding ball having a hardness greater than the hardness of the alloy.
And step two, filling metal mixed powder and grinding balls into the cleaned ball milling tank, sealing the ball milling tank, putting the ball milling tank into a ball milling machine for ball milling for 6-24 hours, so that the metal mixed powder generates mechanical alloying action and interacts with an alloy matrix on the inner wall of the ball milling tank, and the metal mixed powder is adhered to the inner wall of the ball milling tank and diffuses towards the inner wall of the ball milling tank.

In the fourth step, the heat treatment temperature is 500 ℃ and 950 ℃, and the heat preservation time is 10-30 h. The tempering temperature of the low-temperature tempering treatment is 300-500 ℃, and the heat preservation time is 1-4 h.
