摘要: A relation between AS and n of bulk Zr base metallic glasses (BMGs) is developed, where denoted the mixing entropy difference liquid crystal, component number. In terms this relation, > 4 - 5 does not evidently increases which related to glass forming ability. The results are consistent with corresponding critical cooling rates coming from experiments.
