Numerical Simulation of Dimensional Change During Austempering Heat Treatment in Ductile Cast Iron

Mostrar todas las versiones(2)

Changes in the form and dimensions of ductile iron parts occur during the austempering process, and this poses a challenge whenever tight tolerances need to be satisfied. Thus, it is important to be able to predict the deformation which occur under heat treatment to evaluate the minimum and maximum...

Austempered Ductile Iron Dimensional Change Numerical Simulation Finite Element Analysis Changes in the form and dimensions of ductile iron parts occur during the austempering process, and this poses a challenge whenever tight tolerances need to be satisfied.

Moreover, parts could be machined before heat treatment under better mach inability condition. This paper presents a thermo-mechanical-metallurgical formulation to predict the dimensional changes and final microstructure of a ductile cast iron part as a consequence of the austempering heat process. A coupled thermal, mechanical and metallurgical problem is solved using a finite element method, to take into account different coupled and complex phenomena present in this process.
