- •
Novel HfNbTiVSi0.5 refractory alloy with BCC phase and silicides was synthesized.
- •
The alloy has high yield strength and fracture strain of 10.9% at room temperature.
- •
This alloy still has high compression yield strength at elevated temperatures.
- •
Silicides play a significant role on strength increment.
- •
The composite structure is beneficial to the comprehensive properties.
