Susceptibility of crystalline alloys to deformational amorphization during torsion under quasi-hydrostatic pressure
Tóm tắt
Features of the transition of Ni50Ti30Hf20, Ti50Ni25, Zr50Ni18Ti17Cu15, and Fe78B8.5Si9P4.5 crystalline alloys with different susceptibilities to amorphization upon annealing and in the amorphous state during intense deformation in a Bridgman chamber are considered. The single- and two-phase crystalline states of the chosen alloys are obtained in different annealing modes. It is shown that the amorphizing rate of crystalline alloys differ substantially at the same degree of deformation; i.e., single-phase crystalline alloys based on titanium nickelide and iron amorphize well, while zirconium-based alloy amorphizes weakly in a manner similar to two-phase iron alloy. We believe that the LDA of crystalline alloys and their corresponding crystalline phases is determined by mechanical, thermodynamic, and concentration factors.
