Simulation for Quenching

Virtual Heat Treatment Optimization

Quenching is used in the production of cast or otherwise-produced metal components. In particular, immersion or direct quenching processes are widely adopted procedures in the automotive and aerospace industries to minimize the formation of undesirable thermal and transformational gradients, which may lead to increased distortion and cracking.

Le défi

Quenching Simulation

  • Can air quenching and oil quenching be simulated?
  • Is it possible to predict spray quenching?
  • Can I consider the martensitic phase transformation during steel quenching?

 

Residual Stresses

  • How can I localize residual stress concentrations?
  • Do residual stresses depend on processed parameters?
  • Is submerging orientation important?

 

Deformations

  • Can I predict structural deformations of large components?
  • Is stacking of numerous parts important?
  • Are quenchant temperature and agitation relevant?

La solution AVL

AVL FIRE™ offers the unique simulation solution for the quenching process, which is affected by a variety of factors, including initial solid temperature, solid piece orientation or water temperature. The software is architected to accurately predict real-time quenching effects, local temperature gradients and the overall cooling history of complex quenched components – in a single-step approach avoiding time-consuming iterative steps. It has proven to be an accurate numerical tool in numerous complex configurations. Eventually, heat treatment specifics, such as orientation, stacking or quenchant temperature, will influence the nature and the level of residual stresses and deformations.
