| Abstract Scope |
The Pd43Cu27Ni10P20 alloy is a prototypical bulk metallic glass (BMG) former: it possesses a wide supercooled liquid regime (ΔTx) and high resistance to crystallization, permitting casting and shaping under moderate conditions realisable in industrial practice. These factors, coupled with its intrinsic properties, make this Pd-based alloy attractive for practical applications (e.g. biomedical applications). However, this alloy is known to be relatively brittle in the as-cast state (i.e. limited plasticity near room temperature), limiting its use. The properties of a glass are dependent on its state, which, in turn, depends on the cooling rate from which it was formed. Once solidified, it is possible to thermomechanically treat MGs into a different energy state, both higher (‘rejuvenation’) and lower (‘relaxation’). In this work, we investigate the effects of cryogenic thermal cycling on Pd43Cu27Ni10P20 BMG samples, with special focus on the impact of the technique on mechanical properties. |
