Abstract in another language
The problems of structure formation in metals and alloys under their exposure to pulses of various nature are discussed on the basis of crystal shear stability. The structure formation of aluminum and copper alloys is considered during their thermal cyclic treatment using furnace and laser heating as well as under exposure to pulse magnetic field. It is shown that the structure formation in metals with high stacking-fault energy occurs due to glide and climb dislocation processes. Twinning is an alternative to dislocation glide for metals with low stacking-fault energy.
