Physicochemical Processes Accompanying the Plastic Strain Localization under Pulsed Loading

The formation of localized deformation bands is accompanied by the mass transfer of particles of the matrix material (interstitial atoms, impurities, etc.) toward faults in the material being destroyed and by the emergence of stress oscillations in a mode of ultrasonic vibrations lasting several ord...

Description
Summary:The formation of localized deformation bands is accompanied by the mass transfer of particles of the matrix material (interstitial atoms, impurities, etc.) toward faults in the material being destroyed and by the emergence of stress oscillations in a mode of ultrasonic vibrations lasting several orders of magnitude longer than the initial pulse. It was assumed that dislocations generated under pulsed deformation are the cause of the migration of particles.
