Аннотация:The amorphization behavior of the crystalline multicomponent Ni50Ti30Hf20, Ti50Ni25Cu25, Zr50Ni18 Ti17Cu15, and Fe78B8.5Si9P4.5 alloys upon severe plastic deformation (SPD) has been studied. It is shown that the crystalline to amorphous transition is determined by the ability of the crystals to accumulation of deformation defects under mechanical action, by the thermodynamic stability of the crystalline phases contained in the alloy, and by the possibility of the diffusion processes necessary for the change in the chemical composition of the crystalline and amorphous phases upon deformation. It is found that the susceptibility to amorphization upon SPD does not coincide with the tendency of the alloys to amorphization upon melt quenching. (C) 2014 Elsevier B.V. All rights reserved.
