A centimeter-scale BMG sample was obtained for the Ni4Zr9Al2 (Al13.3Ni26.7Zr60 in atomic percent) composition. The thermal glass parameters for this BMG were determined to be ΔTx = 68 K,Trg = 0.579,and γm = 0.689. Using the 'cluster-resonance' model for glass formation an optimal BMG composition was determined using the cluster formula [Ni3Zr9](Al2Ni1). 关键词：大块金属玻璃共振集群 BMG 玻璃形成锆镍铝
