Determination of relaxation and dislocation characteristics of metals on the basis of shock compression diagrams
V. M. Kosenkov Institute of Pulse Processes and Technologies, National Academy of Sciences of Ukraine, Nikolaev, 54018, Ukraine
Abstract:
A method of determining the time of relaxation of shear stresses and characteristics of dislocation structures in the process of shock compression of polycrystalline metals with the use of strain diagrams obtained by the Kolsky method with the help of the split Hopkinson bar is developed on the basis of the rheological Maxwell model and dislocation-kinetic relations. Characteristics of seven types of aluminum-based alloys are analyzed by this method.
Keywords:
Maxwell model, shock compression diagram, Kolsky method, relaxation of shear stresses, density of dislocations, velocity of dislocations, aluminum alloy.
