Preparation, structures and properties of tungsten-containing refractory high entropy alloys

As a new type of multi-principal component solid solution alloy, high-entropy alloy has the four major effects, i.e. high entropy, lattice distortion, slow diffusion, and “cocktail” in orderly arrangement atoms chemical disorder. It exhibits excellent comprehensive performances is expected to be used as high-temperature structural material, wear-resistant radiation-resistant which areas aerospace, mining machinery, nuclear fusion reactors others. In this paper, present research status, conventional preparation methods, microstructures phase compositions tungsten entropy alloys are mainly introduced. view properties alloys, mechanical properties, friction wear resistance, radiation resistance summarized, future directions also prospected.
