“…To solve the problem of an additional increase in the wear resistance of low-alloy steels, it is necessary to improve the technology of heat treatment of steels by studying the features of their structure. Including after determining the structural indicators and the quantitative ratio of the wear resistance index of steels under the conditions of metal-to-metal friction after preliminary cyclic heat treatment, using the method of preliminary cyclic heating and then completed induction heat treatment, which contributes to the maximum use of the nature of steel to increase its wear resistance [6].…”

“…Therefore, it was decided to additionally release some of the samples to the same uniform hardness of 53-54 HRC and 55-56 HRC. Such processing makes it possible to evaluate wear resistance in the formation of the same hardness, and also meet the requirements given in the drawing of fine-grained gear parts [6].…”

“…An analysis of published materials in recent years in the field of heat treatment shows [4][5][6][7] that cyclic heat treatment is currently widely used to improve the structure and properties of steels. On the basis of cyclic heat treatment of steels, some of their mechanical properties are improved, the result obtained is quite effective in comparison with conventional heat treatment technology [5].…”

The heat treatment technology has been improved, which makes it possible to increase the wear resistance of parts of working parts by 30-40%, operating under conditions of metal-tometal friction using preliminary cyclic heating and then pulse hardening. When using the cyclic heat treatment method, the intensity of the diffusion transformation mechanism increases due to repeated accelerated heating and cooling in the stage of incomplete austenite recrystallization and grain growth that has not yet been formed. It has been established that during preliminary reheating, this thermally stable dislocation serves as a source that forms a new dislocation at the αγ -α transition. It was determined that the value of the highest degree of the defect in the crystal structure of steel grade 65G should be preliminarily subjected to three-fold cyclic heating in the temperature range of 450-500°C in the range of 4-5 seconds. As a result of cyclic heating, a lamellar structure was formed in the steel structure and this structure is thermally stable.

We studied carbon steels (from technical iron to Y8) and low-alloy steel 65G. The grades of these steels are regulated by GOST 8559-75. To create different structures in the studied steels, the samples were subjected to heat treatment. The processing modes were selected in such a way as to ensure the study of the effect on wear resistance of one structural parameter of steel with the relative stability of other parameters. The relationships between the parameters of the structure of heat-treated steels and their abrasive wear resistance are established. At all temperatures of the final tempering of hardened steel, there is a direct relationship between its structure parameters (the number of elements in a solid solution, the density of dislocations, the size of cementite particles and the intercementite distance) and wear resistance when sliding friction against loose abrasive particles. A computer program has been developed to select the chemical composition of the steel grade and methods of thermal hardening in order to ensure the required wear resistance.
