“…The FEA model can be used to acquire the distribution of the temperature and residual stress, which could be validated by previously reported experiments (Ref [1][2][3][4][5]. The simulation results played an important role in designing new products and in optimizing the quenching process (Ref [6][7][8][9].…”

Distortion resulting from heat treatment may cause serious problems for precision parts. A precision component made from 30CrNi3Mo steel with internal threads distorts slightly after quenching-tempering treatment. Such a small distortion results in serious difficulties in the subsequent assembly process. The distortion of the internal thread was measured using semi-destructive testing with video measuring system. Periodic wavy distortions emerged in the internal threads after heat treatment. Then both XRD analysis and hardness testing were conducted. A numerical simulation of the complete quenching-tempering process was conducted by DANTE, which is a set of user subroutines that link into the ABAQUS/STD solver. The results from the simulations are in good agreement with the measurement in distortion, microstructure field, and hardness. The effects of the technological parameters including quenchant, immersion orientation, and grooves were discussed on the basis of the simulation results. Finally, strategies to significantly decrease distortion and residual stress are proposed.

“…Heating to high temperature in the cutting process causes the near‑surface zone to become hardened during the rapid cooling of the material. Compressive stresses occur in the hardened zone due to the phase transitions ( Figure 6 a) [ 19 , 26 , 27 , 28 , 29 ]. Based on the conducted research, it is possible to present the mechanism of steel cracking in the thermal cutting process.…”

The paper presents research results of the influence of heat input into high carbon rail steel during cutting processes on microstructure transformation and cracking. The massive block of steel prepared for rail rolling processes was cut and examined by nondestructive magnetic testing and destructive testing by microscopic examination and hardness measurements. The results show unfavorable microstructure changes where pearlite and transformed ledeburite were obtained. The effects of the presence of such microstructures are high hardness near to cutting surfaces (above 800 HV) and microcracks which grow into low hardness block cores during rolling and rail shaping.

“…As a result, a fine-grained martensite phase [4][5][6] and a compressive residual stress field [7][8][9] are induced in the surface layer, which enhances the fatigue life behavior of engineering components [10,11]. However, high temperatures coupled with longer heat time could lead to grain growth (causing a degradation in fatigue strength), data scatter, and excessive gear distortion [12,13]. Accordingly, the control of the process parameters is highly important to validate the effectiveness of this heat treatment process [14].…”

Inverse problems can be challenging and interesting to study in the context of metallurgical processes. This work aims to carry out a method for inverse modeling for simultaneous double-frequency induction hardening process. In this investigation, the experimental measured hardness profiles were considered as input data, while the output data were the process parameters. For this purpose experiments were carried out on C45 steel spur-gear. The method is based on machine learning algorithms and data treatment for dealing with inverse approach issues. In addition to the inverse modeling, a forward problem-based verification completes the study. It was found that according to promising results that this method is suitable and applicable for inverse problem of hardness modeling.
