摘      要：The extreme environment in a fusion reactor,namely high thermal load and intense energetic particles,requires the materials to possess high strength and good ductility at high temperature in combination with excellent radiation *** metal tungsten(W)and its alloy cannot satisfy these rigorous requirements,but the discovery of the W-based high-entropy alloys(HEAs)with outstanding properties sheds light on the developments of structural *** properties of some of these alloys make them promising candidates for engineering applications in fusion reactor beyond conventional W and its *** particular,their strengthening-toughening mechanism has also aroused wide ***,the design,microstructure,mechanical properties and irradiation performance of W-based HEAs are reviewed,and their future prospects are outlined.
