Abstract
The study presents investigation results of the hardening points impact, created on the model surface by means of a laser complex. The authors investigated the change in the steel microhardness in the area which is treated with laser processing and presented the model of stress-strain diagram. The article reveals a change in the yield point and the plasticity of the models as a result. The authors made a number of speckle photos showing the Chernov-Luders lines behavior.
