Abstract

High pressure torsion was applied to produce disk-shape specimen of Cu60 Zr20 Ti20 composition. Radial dependence of the microstructure was monitored by x-ray diffraction, scanning, and transmission electron microscopies. The disk consists of a top surface layer, homogeneous on a micrometer scale with an average thickness of 10-20 μm, and an inhomogeneous bulk region of 200 μm thickness. Calorimetric studies revealed that the disk contains detectable amount of amorphous phase. Characteristics of this amorphous content were compared to a fully amorphous melt-quenched Cu60 Zr20 Ti20 ribbon.
