Abstract

The Sm-based Sm-Al-Ni glass-forming system was investigated using our e/ a-and cluster-related criteria. Three bulk metallic glasses (BMGs) Sm₅₄Al₂₃Ni₂₃, Sm₅₆ Al₂₂Ni₂₂, and Sm₅₈Al₂₁ Ni₂₁, were obtained by suction casting into rods with a diameter of 3 mm. All of them shared a constant e/a = 1.5 and fell along the e/a-constant composition line in the ternary composition chart. The Sm₅₄Al₂₃Ni₂₃ BMG exhibiting the largest T_rg was located at the intersection point of the e/a-constant line and the Sm₇Ni₃-Al cluster line, with thermodynamic parameters of T_g. = 548 K at a heating rate of 20 K/min, T_g/T_m = 0.634, and T_g/T_l = 0.615. The Sm₇Ni₃ cluster was a capped trigonal prism derived from the SmNi phase. © 2007 Materials Research Society.
