BR21882240 “Creation of quasi-high-entropy alloy with the use of Kazakhstani raw materials and technology of production of precision parts on its basis” s.w. Issagulov A.Z.
Relevance
Most of the precision parts of medium and heavy engineering (fittings of gas and oil pipelines, replacement parts of pumps, metallurgical equipment, mining combines, etc.) are currently supplied to Kazakhstan from abroad, which puts the country in economic dependence. Meanwhile, the level of development of metallurgical and foundry production in the Republic of Kazakhstan allows producing its own precision parts from appropriate materials. For example, LWM method (investment casting) and LGM method (casting on gasifiable models) are sufficiently developed, which allow to produce shaped parts of high geometric accuracy and surface cleanliness. It is obvious that the development of own technologies for the production of precision parts is an urgent task of strategic importance for the Republic of Kazakhstan.
Purpose of the program
Development of the composition of quasi-high-entropy alloy (QHEA) using Kazakhstani raw materials and technology of production of precision parts on its basis for medium and heavy engineering.
Expected and achieved results
On the basis of the conducted monitoring the object of research was determined – elements of shut-off and control valves – flanges, sealing rings, disks, which are currently made of high-alloy steels. Structural strength of products and special properties (heat resistance, heat resistance, etc.), as well as structure parameters and phase composition are defined as the subject of research. The FeCrNiCoMn system was determined and justified as the basic system for further studies. The choice of the system is conditioned by good properties demonstrated by alloys of this system. on the basis of the specified system with partial use of ferroalloys as charge components. The obtained results showed the principal possibility of development of this research direction. The raw material base for development and production of KEER with components of Kazakhstani content was determined. Based on the results, an article was submitted to CIS Iron and Steel Review (Moscow, Russia). A program website was created to highlight the scientific results of the Program implementation, transparency of the research team’s activities and to attract potential consumers of the developed technology.
Figure 1 shows the structure of the experimental alloy and the results of MRSA at 4 points. As can be seen from the data in Table 6 and the given characteristic spectrum, Fe, Cr, Mn, Co and Ni are present in the structure, and their concentration practically coincides with the concentration of elements obtained on Poly Spec-F.
The structure of the experimental alloy is represented by a solid solution, presumably of the substitution type with FCC-lattice. The matrix also contains minor inclusions, presumably of silicate nature.

In order to determine the possible risks associated with the presence of inclusions, a quantitative analysis of the main characteristics of the inclusions was performed. Quantitative inclusion characteristics were obtained using Thixomet Pro software (Figure 2)
