Improving the physical and mechanical properties of structural steel by volume of pulsed laser hardening

In the article the need for different methods of strengthening materials to improve their physical and mechanical properties, mainly, such as strength and durability. Moreover, we show the feasibility of methods of strengthening that improve the properties of materials by volume. The article gives a brief description of the method of volume pulse laser hardening, developed in the North Caucasian Federal University. Volumetric method of pulsed laser hardening previously used exclusively for cutting materials (high-speed steel, carbide), which showed positive results. Since previous studies have shown that in high-speed steels after volumetric pulse laser hardening is an allocation of cementite of the martensitic phase, further investigation was taken Armco iron, which contains almost no carbon. Results of the research suggest the effect of space pulse laser hardening of carbon-free materials.
