Embodiment Construction
[0020] The present invention will be further described below in conjunction with specific examples, so that those skilled in the art can better understand the present invention and implement it, but the given examples are not intended to limit the present invention.
[0021] 1. A method for preparing a pre-alloyed CrNiFeTiMoW high-entropy alloy porous material according to this embodiment, the preparation steps are as follows:
[0022] Step 1, raw material weighing: Weigh ultrasonically treated Cr, Ni, Fe, Ti, Mo and W materials according to equimolar ratio;
[0023] Step 2: Atomized powder production: ① put the material weighed in step 1 into a medium-frequency induction melting furnace and melt it into a metal liquid; ② introduce a high-speed jet of argon flow through the nozzle to impact and shear the metal flow, breaking it into fine particles The metal droplet, the nozzle gap size is 0.5~1.0mm, and the spray angle is 30~60°; ③The liquid droplet is quenched in 1.8~2.0MPa p...
