Abstract

Abstract Austempered Ductile Iron (ADI) materials show a good combination of mechanical properties, with high tensile strength levels (800–1600 MPa) and an elongation at fracture of up to 10 %. For that reason ADI is a very attractive material group for applications under cyclic loads. However, the material properties are very sensitive to the applied process conditions during heat treatment. In order to optimize the microstructure in an industrial heat treatment process for ADI castings virtually, several aspects concerning microstructure formation as well as industrial heat treatment process conditions have to be considered in simulation. Coupling process simulation with virtual Design of Experiments offers a new methodology to assess and optimize heat treatment processes.
