THE DEFORMATION MECHANISMS IN METALLIC ALLOYS
https://doi.org/10.17073/0368-0797-2014-8-50-55
Abstract
The main models of the metallic alloys deformation are discussed: the model of the flow due to the presence of defects such as “shear zone”, the model of the free volume and the dislocation mechanism of plastic yielding are considered. For example of MG on the iron base, it is shown that in the metallic alloys at low temperatures the dislocation mechanism of plastic yielding realizes with the activation energy of a few tenths of an electron-volt, whereas at higher temperatures the mechanism of plastic deformation of the flow is going with the activation energy of a few electron-volts, which is close to the activation energy of selfdiffusion and corresponds with two firstly given above mechanisms.
