AUTOWAVE MECHANISM OF LOCALIZATION OF LOWTEMPERATURE PLASTIC DEFORMATION

G.F. Sarafanov & Yu.G. Shodin
The mechanism of localization of low-temperature plastic deformation is investigated within the framework of the thermal activation model. The localization mechanism is considered as a result of the autowave character of the stationary solution of a system of equations that describes both the processes of thermal conductivity and plastic deformation. It is established that the stationary solution of the initial problem is given by the wave fronts of switching waves of temperature and plastic deformation....

Deformation instability in crystalline alloys: Luders bands

G.F. Sarafanov & Yu.G. Shondin
A mechanism of localization of plastic deformation at high temperatures is investigated in the framework of the autowave model. A model of the formation and propagation of Luders bands is proposed. It is established that a Luders band is a wavefront of the plastic deformation rate. From this article's point of view, the conditions for the formation of a Luders band are decisive for the interpretation of the fluidity serration. The critical value of the...
