Abstrakt

Disks of Cu64.5Zr35.5 composition were deformed by high pressure torsion. The cross-section and radial dependence of the microstructure was monitored by X-ray diffraction and scanning electron microscopy. The extreme shear deformation, particularly at the perimeter of the disk promotes the formation of a homogeneous surface layer with a thickness of 10 mu m and the blocks of Cu-enriched regions in the bulk. Calorimetric measurements indicate the presence of a minor amorphous component.
