Purpose and goal

Distortions after heat treatment are one of the biggest challenges in the manufacture of high-performance components. These are caused by a ´distortion potential´ in the component, which is built up through the entire production chain and appears first after hardening. Distortions are very costly. The project goal is to minimize distortion of hardened components by evaluation of the effect from factors causing distortion potential in the process chain.

Expected results and effects

By minimizing the effect of distortion potential built up in the process chain economical and environmental benefits are achieved through shorter processing times, reduced scrap and reduced post operations. Important knowledge in this area are being built, which are specifically urgent due to the generational shift underway within the heat treatment industry.

Planned approach and implementation

During the initiation of the project, important factors controlling the distortion were identified in the process chain. The effect on distortions from these factors will be evaluated by testing, studies of production data and simulations. Guidelines to handle/minimize distortions will be developed.
