Severe plastic deformation induced nanocrystallization of melt-spun Al85Y8Ni5Co2 amorphous alloy
Journal of alloys and compounds, 2008•Elsevier
Rapidly quenched fully amorphous ribbon and disks obtained by high-pressure torsion of
Al85Y8Ni5Co2 composition were investigated by synchrotron X-ray radiation and differential
scanning calorimetry. It was shown that the primary crystalline phase nucleates after severe
plastic deformation is fcc-Al, similarly to isothermal annealing, however, significant
differences in the thermal stability of two processes were detected.
