“…Bouissa et al [23] studied the FEM modeling of phase transformation during quenching of large-size steel forgings; the authors confirmed modeling results by dilatometry test and metallographic examination of the microstructure and obtained very good agreements. A good agreement between hardness measurement and FEM results was also obtained; however, the authors did not simulate the yield and tensile strength of samples.…”

This paper encompasses the development of a microstructure-based numerical model (FEM) of the conveyor cooling process after the hot forging of industrial steel with accurate predictions of the volume fraction of phases as yield and tensile strengths. An experimental procedure for validating the FEM was conducted using optical and scanning electron microscopy and tensile tests. Results showed very good agreement between the phase predictions of the 3D FEM model and those obtained from direct measurement of forged parts, with an average error of about 3.6 and 6.9 % for ferrite and pearlite phases, respectively. Tensile test results were evaluated at a 90 % reliability level, and very good agreements were obtained with an error of about 3 and 5 % for the yield and tensile strengths. The methodology could predict the phase transformations, and the mechanical properties during cooling after the hot forging of the steel were investigated.

In order to improve the performance and mechanical strength of metal parts, manufacturers often need to perform surface heat treatments on these parts. This work requires a lot of experience and prototyping. The objective of our research work is to develop a numerical calculation method using the principles of heat treatment to predict the desired mechanical characteristics and performance in metal parts without any prior experience. This will help manufacturers to reduce a lot of energy and material. The methodology of this work is based on heat transfer laws and heat treatment diagrams: Time-temperature transformation (TTT) and continuous cooling transformation (CCT). Depending on the heating time and the amount of energy applied to the surface of the metal part, we deduce the metallurgical structure and the hardness (HV) that will manifest itself after heating and cooling of this part.
