HIGH-ENTROPY ALLOY CONTAINING BORON AND RARE EARTH AND MAGNETIC FIELD TREATMENT METHOD THEREFOR

摘要

A high-entropy alloy containing boron and rare earth and a magnetic field treatment method therefor. The whole treatment process is divided into two parts, i.e. pulse magnetic field heat treatment and low-temperature static magnetic field treatment. The pulse magnetic field heat treatment has high treatment energy and high treatment efficiency, and can effectively improve the conversion rate of a hard particle phase. The low-temperature static magnetic field further precipitates a particle phase on the basis of inhibiting the growth of grains, significantly refines the grains at the same time, and can effectively relieve internal stress, so that mechanical properties and anti-abrasion properties of the material are greatly improved, and the material has a wide range of applications.
