Influence of boron and cooling rate during solidification on the chemical composition of structural components of complex-alloyed white cast irons of the Fe-C-Cr-Mn-Ni-Ti system

It is possible to improve the technological and operational properties of white high-chromium cast irons by changing the ratio of basic chemical elements in castings, complex alloying, micro alloying and modification, conditions of crystallization of metals in castings and heat treatment methods, which makes it possible to control the process of formation of structure and properties of metal in castings. Structure stability and heat and wear resistance depend on the type and morphology of carbides and the corresponding metal base, chemical composition of structural components that determine the protective properties of oxide layers, since the authors have shown that scale resistance is a structure-sensitive property. The study of the influence of boron and cooling modes in the casting mold on the distribution of chemical elements in the phases of cast irons of the Fe-C-Cr-Mn-Ni-Ti system, ensuring the stability of structure and operational properties at operating temperatures is an urgent task.
