Essay

Iron-based alloys. Investigate structural and phase state after pulse laser treatment. Methods of investigation are experimental one of metals physics. Is shown fixing a residual g-phase in a-iron after laser processing, is established the temperature interval of stability of the received g-phase, is analysed the structure in a zone of laser influence and is appreciated the role of the structural factors in the mechanism of laser hardening, are investigated the laws of formation of residual stresses for various of modes pulse laser processing. Fields of use are all areas of engineering where the improvement of operational properties of superficial layers can be necessary.
