Summary
The alloy's resilience to bending and fracture across an enormous range of conditions could open the door for a novel class of materials for next-generation engines. The alloy is from a new class of metals known as refractory high or medium entropy alloys (RHEAs/RMEAs)
The problem is caused by the formation of kink bands in the metal. Kink bands form when a force is applied to the surface of the metal, causing it to bend. This is why the surface is so tough. The problem is that the kink band can't be removed.
