Abstract

Disks of Cu~64.5~Zr~35.5~ 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 µm and the blocks of Cu‐enriched regions in the bulk. Calorimetric measurements indicate the presence of a minor amorphous component.

Fully amorphous Zr 52.5 Cu 17.9 Ni 14.6 Al 10 Ti 5 (Vit 105) powder with very low oxygen contamination was successfully produced from pre-alloyed crystalline material. A yield of over 80% was achieved without the use of a milling agent. The amorphization process was observed by differential scanning
