摘要：

In order to elucidate the role of total strain and strain rate during high pressure torsion of Al85Ce8Ni5Co2 metallic glass, different deformation conditions were applied to devitrify the as-quenched alloy. The disk-shaped specimens were characterized by X-ray diffraction, transmission electron microscopy and thermal analysis. (C) 2010 Elsevier B.V. All rights reserved.
