Abstract:Two kinds of thermal simulation methods, i.e., stress relaxation method and double-pass compression method, as well as their specific research methods and application examples in the study of the second phase precipitation kinetics curve in steel were systematically introduced. The stress relaxation method used the stress relaxation process of the material to obtain the kinetics curve of the second phase precipitation in the steel at different temperatures. The double-pass compression method was used to study the kinetics of second phase precipitation at different temperatures by double-pass compression of samples in steel. Through practical application, it was found that the stress relaxation method had the advantages of short time and less sample demand, while the double-pass compression method could calculate the starting and ending points of precipitation more accurately, and obtain more accurate data, which was suitable for high-precision research. The application of two methods had achieved good results, which provided a reliable experimental method for the study of the second phase precipitation kinetics curve in steel. Moreover, they provided an important reference for the R&D and engineering design in metallurgical process of steel.
