Excessive distortion can ruin hours of work on parts that are machined and hardened\. Reworking the parts may be challenging, and scrapping the parts leads to lost revenue\. In 1995, the German Research Association of Drive Engineering estimated annual losses of ~850M Euros to remove distortion from manufacturing \[1\]\. Around the same time DANTE, a heat\-treatment process modeling tool, was born from a project with the American automotive industry, academia, and the national labs, to combat distortion in excess of hundreds of millions of dollars annually\. All distortion from heat treatment can be broken down into two categories: shape change and size change\. Size\-change distortion is caused by the reorientation of the crystal structure as the steel changes phase and is unavoidable\. Shape change is the difference in part dimensions before and after hardening, assuming no volume change\. Shape and size change is caused by material, geometry, and process effects\. Material effects refer to the initial state of the steel, including the microstructure phases, chemical composition, carbide phases and sizes, alloy segregation, grain size, and the effects from the material fabrication process\. Part geometry affects distortion due to differences in heating and cooling between thick and thin sections, causing material strain\. Process uniformity and consistency directly affect part distortion during heating and cooling due to the accompanying phase transformations\. Chemical gradients of carbon and nitrogen play a role in nonuniform phase transformations due to their effect on martensite start temperature\. The volume change from tempering martensite can have a similar effect if the thermal gradient is high\. Process consistency and residual stresses from previous processes also impact process distortion\. - [Heat Treatment Process Development for Gears Using Computer Modeling​](https://dante-solutions.com/case-study/heat-treatment-process-development-for-gears-using-computer-modeling-test/): For this process, the LPS model was executed for 4120 steel, with a goal of at least 60 HRC surface hardness, and with an effective case depth of 1\.5mm\. The recipe generated from the carburization tool was then used in a finite element model for analysis of the part\. - [Correcting Bevel Gear Distortion from Heat Treat](https://dante-solutions.com/case-study/correcting-bevel-gear-distortion-from-heat-treat/): Nonuniform and excessive distortion of the tooth in the axial direction during oil quenching\. Machining to correct distortion removes residual compressive stresses, damaging the fatigue performance\. Problem not discovered until after production began\. Cost to correct at this stage is very high\. - [Bearing Ring Cracking in Press Quenching](https://dante-solutions.com/case-study/bearing-ring-cracking-in-press-quenching/): The basis of this study is a 4” OD bearing ring, made of AISI 52100 steel\. A large number of these bearing rings were failing during the press quenching process, as seen in the table\. Large circumferential cracks could be seen in the bearing race in over half of the parts after quench and temper\. - [Improving Gear Tooth Bending Fatigue Life](https://dante-solutions.com/case-study/improving-gear-tooth-bending-fatigue-life/): Helicopter transmission life limits load carrying capacity and acceleration\. Improved gear bending fatigue life will allow heavier loads and improved acceleration\. New designs are costly and require long development times\. A process improvement for an existing design saves time and money\. ## Publication - [Residual Stress and Bending Fatigue Strength in Carburized and Quench Hardened Pyrowear 53 Steel Gears](https://dante-solutions.com/publication/residual-stress-and-bending-fatigue-strength-in-carburized-and-quench-hardened-pyrowear-53-steel-gears/) - [Probe Design to Characterize Heat Transfer during Quenching Process](https://dante-solutions.com/publication/probe-design-to-characterize-heat-transfer-during-quenching-process/) - [Integrated Heat\-Treatment Simulation with Virtual Inspection of Distorted Gears](https://dante-solutions.com/publication/integrated-heat-treatment-simulation-with-virtual-inspection-of-distorted-gears/) - [Heat Treatment Process Exploration with HTP Sim](https://dante-solutions.com/publication/heat-treatment-process-exploration-with-htp-sim/) - [Modeling the Effect of Carburization and Quenching on the Development of Residual Stresses and Bending Fatigue Resistance of Steel Gears](https://dante-solutions.com/publication/modeling-the-effect-of-carburization-and-quenching-on-the-development-of-residual-stresses-and-bending-fatigue-resistance-of-steel-gears/) ## case study topics - [Stress](https://dante-solutions.com/case-study-topic/stress/) - [Distortion](https://dante-solutions.com/case-study-topic/distortion/) - [Induction](https://dante-solutions.com/case-study-topic/induction/) - [Quench](https://dante-solutions.com/case-study-topic/quench/) - [Analysis](https://dante-solutions.com/case-study-topic/analysis/) ## publication topics - [Residual Stress](https://dante-solutions.com/publication-type/stress/residual-stress/) - [Carburization](https://dante-solutions.com/publication-type/carburization/) - [Oil Quench](https://dante-solutions.com/publication-type/quench/oil-quench/) - [Tempering](https://dante-solutions.com/publication-type/tempering/) - [Distortion](https://dante-solutions.com/publication-type/distortion/) ## Resource Types - [Article](https://dante-solutions.com/resource-type-draft/article/) ## video types - [Animation](https://dante-solutions.com/video-type/animation/) - [Abaqus Tutorial](https://dante-solutions.com/video-type/tutorial/abaqus-tutorial/) - [Webinar](https://dante-solutions.com/video-type/webinar/) - [Ansys Tutorial](https://dante-solutions.com/video-type/tutorial/ansys-tutorial/) - [Utility Tutorial](https://dante-solutions.com/video-type/tutorial/utility-tutorial/) ## Optional - [Sitemap index](https://dante-solutions.com/sitemap_index.xml)
