1. A preparation method of a metal powder material, comprising the following steps:
providing an alloy sheet, wherein the composition of the alloy sheet is MaNb, M is Cu, N is selected from the group consisting of W, Cr, Mo, V and mixtures thereof, and a and b represent the atomic percentage content of the corresponding element, and 0.1%≤b≤45%, a+b=100%; the microstructure of the alloy sheet is composed of a matrix phase with component M and a dispersive particle phase with component N; and
making the alloy sheet react with an acid solution, so that the matrix phase with component M reacts with H+ of the acid solution to become metal ions to enter the solution, and the dispersive particle phase with component N is separated, and the metal N powder material is obtained.
