Crystal-to-Amorphous Transformation Induced by High Pressure Torsion in Zr-Cu-Al Alloys

摘要

Crystal-to-to-amorphous transformation by introduction of lattice defects using plastic deformation has been regarded as potential technique to produce materials with both amorphous and nanocrystalline structure. In this study, we employed high pressure torsion (HPT) to fabricate amorphous-nanocrystalline structure via crystalline-to-amorphous transformation (CTAT) in Zr50Cu46Al4 (4Al), Zr50Cu44Al6 (6Al) and Zr50Cu40Al10 (10Al) alloys.
