Abstract:

Addition of a small amount of La and Co enhances the stabilization of supercooled liquid and glass-forming ability (GFA) of an Al₈₅Ni₇Er₈ metallic glass. The Al₈₅Ni₅Co₂Er₆La₂ alloy exhibits large super-cooled liquid region of 40 K, high GFA with a critical thickness of 450 mm, and the viscosities on the orderof 10⁷-10⁹ Pa s in the supercooled liquid state. The Al-based glassy nano-scale patterns were formed by imprinting, indicating its good thermoplastic formability. The possible mechanism for the improvement of the supercooled liquid stability of the Al-Ni-Er alloy by addition of La and Co elements was discussedin terms of the crystallization behavior.
