Effects of homogenizing annealing on the reduction of crack formation in forgings of steel grade 08Kh18N10T

Abstract
Experimental data on crack formation of forgings made of austenitic steel grade 08Kh18N10T are presented. It has been established that the process of crack formation is determined by the process of homogenizing annealing, which is carried out during heating of ingots and forgings before the first and second removals. The development of a technology for forging large ingots made of austenitic steel grade 08Kh18N10T, taking into account these results, leads to an increase in the quality of forging and makes it possible to achieve forging without cracking.
Supporting agencies: Experimental studies were performed on the equipment of the Center for Collective Use “Composition, Structure and Properties of Structural and Functional Materials” of the NRC “Kurchatov Institute” – CRISM “Prometey” with financial support from the Ministry of Science and Higher Education of the RF, Agreement 13.TsKP.21.0014 (075-11-2021-068), unique identifier RF-2296.61321X0014
