Effect of Controlled Thermomechanical Processing Routes on the Structural and Textural States of Low-Carbon Low-Alloy Steel

The method of orientation microscopy (EBSD) is used to study the structural and textural states of samples of low-carbon low-alloy steel of type 06G2MB subjected to thermomechanical controlled processing (TMCP) by five pilot routes differing in the finishing hot-rolling temperature and in the intens...

Description
Summary:The method of orientation microscopy (EBSD) is used to study the structural and textural states of samples of low-carbon low-alloy steel of type 06G2MB subjected to thermomechanical controlled processing (TMCP) by five pilot routes differing in the finishing hot-rolling temperature and in the intensity of the controlled cooling. The interrelation between the processing parameters, the structure and the mechanical properties of the samples is determined. It is shown that the TMCP route with the finishing hot-rolling temperature close to A 3 and maximum cooling intensity is the most optimal treatment.
