文摘

FeCoCrNiW0.3 high entropy alloy predicted and synthetized. Slip bands around indentation marks could indicate alloy with stacking fault energy. Addition of 5 at.% of C to FeCoCrNiW0.3 produces hard carbides in HEA matrix. Good resistance to oxidation in 700–900 °C range. Hardness and scratch hardness compare well with conventional more expensive alloys.
