Zusammenfassung: | The invention relates to the technical field of powder metallurgy materials, and particularly discloses a CrAlCuFe alloy target material and a preparation method thereof. The CrAlCuFe alloy target material is of a (BA) nB structure, A is a CrAlCuFe alloy target layer, B is a TiAl alloy bottom layer, and n is equal to 1-15. The invention further discloses a preparation method of the alloy target material. The CrAlCuFe target layers and the target layers and the sheath are separated by the TiAl bottom layer, and meanwhile, pre-alloying heat treatment is set, so that Al and Cu/Fe in the sheath are pre-alloyed to a certain degree, heat release caused by severe alloying reaction in the HIP process is reduced, and the problem of sheath melting and the problem of cracking of the Fe-containing alloy target material prepared by a hot isostatic pressing process are solved.
