Ternary Sm-Al-Co Bulk Metallic Glass Formation Designed Using a Cluster Line Approach

Abstract:

Article Preview

Ternary Sm-Al-Co bulk metallic glass formation is investigated with the guidance of a cluster line approach which is defined by linking a special cluster composition to the third element in the ternary phase diagram. Two dense-packed cluster lines Sm6Al3Co2-Co and Sm8Al1Co4-Al are constructed and they intersect at a good BMG composition Sm50Al25Co25. This composition can also be interpreted with a cluster-plus-glue atom model. The characteristic parameters of this optimum BMG are respectively Tg = 579 K, Tx = 640 K, Trg= 0.648, γ = 0.435 and E=244 kJ/mol.
