Temperature induced phase evolution in metallic glasses

Orava et al. performed an in-situ XRD study of Cu-Zr-Al metallic glasses in order to map the phase evolution with respect to temperature. Ribbon samples were used and followed a flash-annealing up to a temperature of ~ 1200 K where the heating rate was ~1100 K/s. The chamber was either under vacuum or flushed with He (allowing a faster cooling). Identification of the crystalline phases which form upon cooling was possible, including the dependence of cooling rate. This study also used an electromagnetic levitation device for in-situ XRD, described in ref. [10].

Experiments were performed at the Swedish Materials Science beamline, P21.1 branch.
