Description
Summary:The behavior of flat specimens made of 40X13 (40Kh13) corrosion-resistant steel after laser hardening and laser alloying under bending loading was studied. The processing was performed using a continuousaction ytterbium fiber laser LK-1000 with a scanning system. Tracks 4 mm wide were applied along one or both sides of the specimen, the number of tracks varied from two to six. The tests were carried out on a Kason WDW-50 testing machine. The test results showed that the presence of laser exposure leads to a decrease in the specimen deflection achieved before failure and an increase in the level of the perceived maximum load. The test results of alloyed and hardened specimens showed a decrease in the plasticity of the material after laser processing with a simultaneous increase in the maximum perceived loads, with a more significant change in the material properties obtained with laser hardening. Failure of the specimens has a pronounced brittle nature by tearing off from the action of longitudinal normal stresses. Studies have shown that higher levels of perceived load are achieved with double-sided processing. Specific results depend on the implemented material processing modes.
