In this article, the author explores the standard process of bending straightening on a carburized pinion gear shaft. To do so, computer-aided engineering (CAE) analysis is used to simulate the process but accurate information about its heat treatment history is needed to accurately calculate not just the distortion but also the case depth and material composition.

This study uses a carburized Pyrowear 675 Almen strip to isolate and quantify causes of quench distortion during heat treating by measuring bow distortion after each processing step and comparing that to simulated results.

This article is an introduction of some aspects of modeling in thermal treatments in heat treated components. it introduces the mathematical models and physical fields required for modeling with a primary interest in hot-treated components but also talks about modeling residual stress in welding or additive manufacturing (AM).

This article focuses on the important considerations when modeling residual stress including constitutive models, mesh and part discretization, calculation methods, material properties, boundary conditions, and FEM modeling. Further, this article explains the effects of the heat-transfer coefficient and phase transformations.

This article introduces the various techniques related to the prediction and simulation of residual stresses in steel parts generated by thermochemical surface treatments such as atmospheric carburizing, low pressure (vacuum) carburizing, gas nitriding, etc.

This article is an introduction into simulating quenching cooling rates and the challenges involved with modeling residual stresses during quenching; focusing on prediction methods for quenching surface heat-transfer rates.

This article discusses the material, thermal, and mechanical properties needed to simulate residual stress it metal components.

An experiment meant to evaluate and then optimize experimental heat treatment processes for a AISI 9310 steel carburized gear using commercially available programs: ABAQUS and DANTE. A process model was created and then optimized using the sin2ψ technique.

This article discusses the stress changes during cyclic loading in steel parts, specifically high-cycle (HCF), manufactured through carburizing, quench hardening, and shot peening.
