Application of thermochemical treatment for creation of metastable modifications realizing the effect of selfstrengthening at steel wear

Application of thermochemical treatment for creation of metastable modifications realizing the effect of selfstrengthening at steel wear

Abstract

It was proposed to solve urgent problems of saving scarce and costly high-alloyed and wear resistant steel grades (containing Ni, Mo, V, W, Nb) and increasing wear resistance of metal parts by means of creating surface modifications of metastable phase-structural complexes in inexpensive economical alloys of the similar structural classes. The objective of this work is to investigate the influence of alloying elements upon the formation of the structure, metastability of austenite and properties of chromium-manganese steel grades, undergoing carburizing and manganese steel undergoing decarburizing. In this work the new ways and processes of surface modifications of metastable phase-structural states were developed:carburizing Fe-Cr-Mn steels with various contents 2…22 % Cr with subsequent quenching at optimal temperatures of austenitization;decarburizing austenitization for a specified depth of high-alloyed wear resistant steel grades (110Mn13 Hadfield steel, 130Cr12Mo etc.) causing destabilization of austenite and realization deformation induced martensite γ→α′ transformation in the process ofwear.

Предложено решение актуальных проблем экономии дефицитных и дорогостоящих высоколегированных и износостойких марок стали (содержащих Ni, Mo, V, W, Nb) и повышение износостойкости металлических деталей путем создания поверхностных модификаций метастабильных фазово-структурных комплексов в недорогих экономичных сплавах подобных структурных классов. Целью данной работы является исследование влияния легирующих элементов на формирование структуры, метастабильность аустенита и свойств хромо-марганцевых марок стали после цементации и марганцевой стали после обезуглероживания. В этой работе были разработаны новые способы и процессы поверхностных модификаций метастабильных фазово-структурных состояний:цементация Fe-CrMn сталей с различным содержанием 2... 22 % Cr с последующей закалкой при оптимальных температурах аустенитизации; обезуглероживающая аустенитизация на определенную глубину высоколегированных износостойких сталей (110Г13 сталь Гадфильда, 130Х12M и т.д.) вызывающая дестабилизацию аустенита и реализацию деформационного мартенситного γ → α ' превращения в процессе изнашивания.
