Kink bands promote exceptional fracture resistance in a NbTaTiHf refractory medium-entropy alloy | Science

Single-phase body-centered cubic (bcc) refractory medium- or high-entropy alloys can retain compressive strength at elevated temperatures but suffer from extremely low tensile ductility and fracture toughness. We examined the strength and fracture …
