Abstract

The paper present the concept of a mathematical model for predicting changes in the microstructure of the austenite steel for cold upsetting, the research was carried for 30MnB4 23MnB4 steel grade. Microstructure evolution model is based on the classic Sellars model developed by taking into account the parameters of plastic forming processes and their impact on the processes occurring in the deformed steel. The coefficients of mathematical equations describing the evolution of deformed austenite microstructure were calculated based on the results of experimental studies carried out in the Institute of Plastic Working and Safety Engineering Czestochowa University of Technology.For the verification of the accuracy developed model laboratory studies were conducted using a metallurgical processes simulator Gleeble 3800. Comparison of the results obtained in the theoretical and experimental studies have confirmed good agreement developed model of the microstructure evolution for the steel with boron for a cold upsetting.
