Are the abilities of crystalline alloys to amorphization upon melt quenching and severe plastic deformation identical or different

Abstract The amorphization behavior of the titanium-nickelide- and zirconium-based crystalline alloys, which differ in the ability to amorphization upon melt quenching, have been studied upon severe plastic deformation. It was found that the ability to deformation-induced amorphization upon severe plastic deformation of crystalline multicomponent alloys is determined by the cumulative ability to deformation-induced amorphization of crystalline phases contained in the alloy. It is shown that the parameters characterizing the ability to the formation of amorphous state upon melt quenching and upon high-pressure torsion are substantially different and are controlled by different physical parameters.
