High mixing entropy bulk metallic glasses
WebApr 20, 2024 · Researchers have designed a series of novel high-entropy metallic glass-formers only from the aspect of entropy of mixing [ 17 – 19 ]. Meanwhile, some methods based on combining microstructure and thermodynamics also work well in developing Zr-based glass-formers [ 9, 11, 20 ]. WebThe high-mixing-entropy bulk MGs are then loosely defined as metallic glassy alloys containing five or more than five elements in equal or near-equal atomic percent, which have relatively high mixing entropy compared with the conventional MGs based on a single principal element.
