Amorphous ribbons of compositions (Ni 56 Cu 2 )Zr 18 Ti 13 Al 6 Si 5 and (Ni 36 Cu 23 )Zr 18 Ti 14 Al 5 Si 4 were consolidated by high pressure torsion (HPT) at room temperature. In the HPT experiments a 6GPa pressure and two turns were applied. Samples in the form of discs, 6–7 times thicker than the ribbons and about 10mm in diameter were achieved. The minimal deformation for the homogenous consolidation was estimated to be in the range of 400%. XRD showed that the microstructure was dependent on the composition. The sample with high Cu content remained amorphous while the sample with low Cu content revealed some crystallization. DSC experiments allowed a comparison of the glass transition temperature T g and crystallization process of the amorphous ribbon and HPT sample which were different. The glass transition temperature T g of the amorphous HPT sample of (Ni 36 Cu 23 )Zr 18 Ti 14 Al 5 Si 4 composition decreased. For both alloys the nanohardness and the elastic modules showed decrease for cold consolidated samples in comparison to the ribbons.
