Stimulation of shear-transformation zones in metallic glasses by cryogenic thermal cycling
Abstract
Cryogenic thermal cycling (CTC, between room temperature and 77 K) of a (Cu,Zr)-based bulk metallic glass(MG) leads to substantial reductions in the initial yield loadFyobserved on instrumented indentation, and canreverse annealing-induced increases inFy. In contrast, for hardness and elastic modulus, CTC has much less effectand can only partially reverse annealing effects. The distribution ofFyvalues is wide, reflecting heterogeneity inthe MG. For a melt-spun Fe-based glass, CTC with more cycles induces similar changes inFy, and has almost noeffect on the magnetic properties. Such differing effects of CTC can be consistently interpreted in terms of itspreferential effect onsoft spotsin a relatively rigid glass matrix. The capability for targeted stimulation ofshear-transformation zonespermits tailoring of MG properties, clearly facilitates initiation of plasticflow, and offers theprospect of improved plasticity and toughness even in annealed samples.
