Compositional features of bulk metallic glasses analyzed with a tetrahedral composition diagram from s-, p-, d- and f-blocks

Abstract

Abstract The compositional features of bulk metallic glasses were statistically analyzed with an s–dEf–dLpM–pMLD tetrahedral composition diagram comprising s-, p-, d- and f-blocks in the periodic table, early- and late-transition metals and Metal–Metalloid. The s–dEf–dLpM–pMLD diagram was filled with 25 BMGs with critical diameter over half-inch (∼12.7 cm), 264 BMGs with the critical diameter ranging 0.2–12 mm, 6150 amorphous alloys from 351 ternary systems and 35400 compounds. The analysis revealed that BMGs as well as the ternary amorphous alloys are principally plotted on s–dEf–dLpM and dEf–dLpM–pMLD faces and their edges and vertices, whereas no plots are seen in s–pMLD edge and deep inside the diagram of each component of s, dEf, dLpM or pMLD ≥10 at.%. The s–dEf–dLpM–pMLD tetrahedral composition diagram is a useful tool for alloy design of bulk metallic glasses.
