The invention relates to the technical field of
powder metallurgy preparation of
refractory metal materials, and specifically discloses a preparation method of a
powder metallurgy refractory multi-principal-element high-entropy
alloy. The preparation method of the
powder metallurgy refractory multi-principal-element high-entropy
alloy specifically comprises the following steps: step S1, refractory
metal element powder is sieved through a 300-mesh
sieve and mixed in a multi-element powder mixing mode, so that a mixture is obtained; the mixture comprises at least four elements of Ti, Zr, Hf, V, Nb, Ta, Cr, Mo and W; the atomic percent of each element in the mixture is 5%-35%; and the total percentage is 100%; step S2, pressing forming is carried out, and a pressed blank is obtained; and S3, vacuum high-temperature
solid-phase
sintering is carried out to obtain a sintered block. The preparation method of the
powder metallurgy refractory multi-principal-element high-entropy
alloy has the advantages that the components are easy to regulate and control, the production efficiency is high, and near-net forming is achieved; the prepared
powder metallurgy refractory multi-principal-element high-entropy alloy is stable in structure and performance and low in cost; and the
powder metallurgy refractory multi-principal-element high-entropy alloy has remarkable advantages in research and development of high-performance powder metallurgy refractory multi-principal-element high-entropy alloy and flexible
batch production of products of various shapes and varieties.
