文摘

Refractory HfMo0.5NbTiV0.5Six high-entropy composites are prepared successfully. Multi-component silicide (Hf, Nb, Ti)5Si3 is generated with adding Si. The addition of Si reduces the density and improves the hardness and strength. Silicides play a significant role on strength increment. The composite structure is beneficial to the comprehensive properties.
