Purpose of the development: Improved quality and competitive capabilities of metal.

Recommended application field: Metallurgy, mechanical engineering.

Advantages over analogues: Almost all the studies carried out in this paper are original results were obtained for the first time. Using modern methods of research confirms the accuracy of the data. The results correspond to the world standards and make a significant contribution to modern metallurgy alloys

The development stage readiness: tested in laboratory condition

Technical and economic effect: The problem of non-metallic inclusions is one of the urgent problems faced by steelmakers and metallurgists who are engaged in production and processing of high quality steel. Therefore, these results are important for its influence on the level of production quality and competitive steel.

Description of the development:
()
Nonmetallic inclusions and phase boundary inclusion are active -matrix elements of the structure of steel. Complex investigations of phase boundaries between the switch matrix showed that education possible orientations match at these boundaries , and their structures were determined by the values of the parameter mismatch of crystal lattices of inclusion and the matrix . Interphase boundaries have different cohesive strength , which can be modified by a variety of high- action , which include high-temperature annealing , hot plastic deformation , laser processing . Experimentally verified computational studies that have identified different types of boundary structure including matrix , and specific limits defects ( interfacial dislocations, stacking faults dimensional ) . The features of high- impact treatments on the mechanism of formation of microfractures near inclusions , certain parameters of inclusions and micro damage under tensile strain . Mechanisms of relaxation processes taking place in the interfacial inclusion matrix during annealing , hot deformation and laser treatment ( vakansiynoy or thermal -diffusion , dislocation- ductile phase , diffusion- opolzneo phase ) that lead to the restructuring of borders including matrix and significantly affect their cohesive strength . It is possible to develop a means of influencing the structure and cohesive strength of the boundaries of inclusion -matrix steel.
