Prealloyed CrMoNbTiZr porous high-entropy alloy and preparation method thereof

The invention discloses a porous filter material taking a prealloyed CrMoNbTiZr high-entropy alloy as a raw material and a preparation technology of the filter material. A powder atomization technology and a powder metallurgy process are combined. The process of preparing the porous material comprises the following steps: weighing metal raw materials such as Cr, Mo, Nb, Ti and Zr according to an equal molar ratio or a nearly equal molar ratio, melting into metal liquid in a medium frequency induction melting furnace, and performing gas atomization to become prealloyed solid powder; doping gluewith powder, drying, performing compression molding, and performing vacuum sintering, thereby obtaining the material disclosed by the invention. The preparation process disclosed by the invention hasthe advantages of being simple, environmentally friendly, short in sintering cycle, easily controllable in pore, high in mechanical strength of the porous material, stable in chemical property, highin corrosion resistance, re
