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

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 de...

Description
Summary: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. [Display omitted] •The abilities to the formation of amorphous state upon MQ and upon SPD radically differ.•Various phases composing multiphase alloys differ in the ability to amorphization upon SPD.•The crystalline alloys exhibit different abilities to amorphization upon MQ and upon SPD.
