I find it remarkably cool that this high entropy alloy (and yes it is an HEA) is so much tougher than everything else known. In tests at 20 kelvin, the CrCoNi displayed a toughness of 500 megapascals square root meters. Aluminium used in aircraft would only be about 35, and the best steels are around 100. And the amount of novel alloys you could get just by fractionally adjusting the percentage of each element is phenomenal. There's just so much potential out there
