What is tungsten-containing high-entropy alloy?
Tungsten-based alloy is a kind of alloy material made of refractory metal tungsten as hard phase and nickel, iron, copper or silver metal as binder phase through powder metallurgy method or injection molding technology, which has quite excellent thermal, mechanical, electrical and chemical properties and is widely used in aerospace, military, national defense, automotive, medical and other fields.
Composed of tungsten, molybdenum, titanium and other five or more major elements in equal or nearly equal material quantity ratio, and each element accounts for 5-35% of the total composition of the alloy, it is a new material with unparalleled performance advantages over traditional alloys in terms of stability of the phase structure, strong toughness, corrosion resistance and resistance to irradiation, etc., and is suitable to be prepared by vacuum arc melting method.
