Recent progress of tungsten-based high-entropy alloys in nuclear fusion

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 resistance. Conventional 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...
