Microstructure evolution and plasticity in Zr-based glass-forming alloys -art. no. 021602

The microstructure characteristic scale, in partially devitrified Zr-based glass-forming alloys, is examined in the light of classical nucleation and growth theory. It is then related to the high-ductility properties of these materials. Stabilization of the icosahedral phase under addition of isoele ctronic elements, as evidenced in recent experiments, is discussed on a qua litative basis.
