Combinatorial measurement of critical cooling rates in aluminum-base metallic glass forming alloys

Abstract Direct measurement of critical cooling rates has been challenging and only determined for a minute fraction of the reported metallic glass forming alloys. Here, we report a method that directly measures critical cooling rate of thin film metallic glass forming alloys in a combinatorial fash...
