Deformation induced crystallization in an amorphous Cu60Zr20Ti20 alloy by high pressure torsion
Abstract Crystallization of Cu 60 Zr 20 Ti 20 amorphous ribbon induced by severe plastic deformation and by linear heating thermal treatment has been compared using differential scanning calorimetry, X-ray diffraction and in situ synchrotron radiation. Thermal treatment of the as-quenched ribbon results in the joint formation of hexagonal Cu 2 ZrTi and hexagonal Cu 51 Zr 14 crystalline phases, on contrary, intensive plastic deformation at room temperature induces the precipitation of only one hexagonal phase.
