The latest advancements in steel grades and in case hardening technology are of key importance to meet the demand for improved fatigue properties of gear components.
A developed set of predictive models to anticipate ring gear dimensional changes that occur during carburizing and hardening may eliminate the need for heat treat test lots and reduce gear development lead time and cost.
The coupling of CFD and heat treatment analyses provides a more robust application of computer modeling to predict the latent heat release, distortion, and residual stresses during the quench hardening process.
Results of a full-scale 3D simulation is utilized to evaluate the complete distribution of residual stress in an induction hardened aeronautic gear component.
The hardening of materials by laser is a specialized and fast-growing field, as it offers improved wear resistance, expansion of component life, and increased strength and fatigue limits of the material.
The success of a nitriding process depends on the ability to meet metallurgical requirements involving microstructures, surface hardness, case hardness, and, in some cases, the part’s appearance.
Among heat treatment techniques, carburizing is one of the most widely used for case hardening.
Understanding the properties, fatigue limits, and designations of stainless steels used in heat treatment processes can be helpful in selecting the right one for specific applications.
