BRIEF REVIEW OF THE INFLUENCE OF THE CHEMICAL COMPOSITION AND THE PARAMETERS OF DISLOCATOR SUBSTRUCTURESOF HADFIELD STEEL ON THE MECHANISMS OF ITS HARDENING AND PLASTICITY

Abstract

At present, the mechanisms of hardening and ductility of Hadfield steel are in the center of attention of world scientific research, representing significant scientific and practical interest in relation to specific technological processes. In particular, an urgent task is to increase the service life of cast steel parts by providing higher steel properties and especially its impact strength and the development of new technological methods that increase the service properties of steel castings for railway transport. Recently, there has been a tightening of requirements for the mechanical properties of cast parts of railway transport, which, however, is not yet fully ensured by the existing technologies for their manufacture.

The aim of this 10-year review of open source scientific literature is to critically review research on the mechanisms of hardening and ductility of Hadfield steel, to identify the main factors described in the scientific literature that affect the formation of the microstructure and mechanical properties of Hadfield steel, in order to present the latest achievements in this field and challenges associated with the prospects for their industrial implementation.

In particular, special attention is paid to the analysis of the influence of the parameters of dislocation substructures and the chemical composition of the Hadfield steel on the mechanisms of its hardening and ductility, in order to identify patterns that will make it possible to give recommendations on the heat treatment of steel or on acceptable and desirable deviations in its chemical composition. It is expected that this review will stimulate closer collaboration between researchers in various fields, including the production, processing and properties of Hadfield steel, as well as further developments for industrialization.
