Abstract

The compositional features of bulk metallic glasses were statistically analyzed with an s-d Ef-d LpM-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-d Ef-d LpM-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, 6 150 amorphous alloys from 351 ternary systems and 35 400 compounds. The analysis revealed that BMGs as well as the ternary amorphous alloys are principally plotted on s-d Ef-d LpM and d Ef-d LpM-pMLD faces and their edges and vertices, whereas no plots are seen in s-p MLD edge and deep inside the diagram of each component of s, d Ef, d LpM or p MLD ≥10 at.%. The s-d Ef-d LpM-pMLD tetrahedral composition diagram is a useful tool for alloy design of bulk metallic glasses.
