High-entropy alloys - microstructures and properties

, 2015
There are relatively few revolutions in the venerable and rather staid field of metallurgy. One can count among them the advent of metallic glasses, of superplastic metals, of memory-alloys and - on the purely theoretical side - of quasicrystals.
