2.6.1. Metal science and heat treatment of metals and alloys

Metal science and heat treatment is a field of science and technology that studies the relationship between the chemical composition, crystal structure, structural state and properties of metals and alloys; development of physical and chemical foundations for the creation of new metallic materials with desired properties and new technological processes of thermal, chemical-thermal and thermomechanical processing.

The importance of solving scientific and practical problems of this specialty for the national economy lies in the creation of new metallic materials with a given level of physical, mechanical, chemical, technological and operational properties, ensuring a high level of stability of these properties, which makes it possible to efficiently and rationally use metals and alloys in fundamentally new designs and types of machines, devices, units, thereby ensuring scientific and technological progress.

Research areas:

- Study of the relationship between chemical and phase compositions (characterized by various types of diagrams), including phase diagrams with physical, mechanical, chemical and other properties of alloys.

- Theoretical and experimental studies of phase and structural transformations in metals and alloys occurring under various external influences.

- Theoretical and experimental studies of the influence of the structure (type, quantity and nature of the distribution of defects in the crystalline structure) on the physical, chemical, mechanical, technological and operational properties of metals and alloys.

- Theoretical and experimental studies of thermal, thermoelastic, thermoplastic, thermochemical, thermomagnetic, radiation, acoustic and other effects of changes in the structural state and properties of metals and alloys.

- Theoretical and experimental studies of the influence of the phase composition and structural state on the initiation and propagation of cracks under various types of external influences.

- Development of new and improvement of existing technological processes for volumetric and surface thermal, chemical-thermal, thermomechanical and other types of treatments associated with thermal exposure, as well as specialized equipment.

- Study of the interaction of metals and alloys with external environments in the conditions of operation of various technical devices, assessment and prediction on this basis of the performance of metals and alloys.

- Study of the performance of metals and alloys in various conditions, selection and recommendation of the most economical and reliable metal materials for specific technical purposes in order to reduce metal consumption, increase the service life, increase the level of specified physical and chemical characteristics of machine parts, mechanisms, devices and structures.

- Development of new principles for creating alloys with a given set of properties, including those for operation in extreme conditions.

- Development of new and improvement of existing methods of phase, structural and physico-chemical analysis of alloys.

- Determination of the mechanisms of influence of various mechanical, thermal, magnetic and other external influences on the structural state of metallic materials and the development on this basis of new principles and methods for testing them, providing reliable prediction of the performance of structures.
