Abstract

The development of metal physics and physical materials science in the coming decades is one of the main driving forces of the new scientific and technological revolution, which will cause significant changes in many sectors of industry and energy, construction and agriculture, military equipment and everyday life. In the work using the principles of nonequilibrium thermodynamics develop new models of solid-phase transformations in iron-carbon alloys: annealing, tempering, γ→α – transformation, graphite formation, carbides transformation. Developed models of solid-phase transformations applied to the management of the structure formation of iron-carbon alloys and optimization of their thermal treatment and identifying the conditions of formation of dispersed (nano) particles of carbides in some of the investigated alloys and possibilities of their transformation.
