Modeling of GP (I) zone formation during quench in an industrial AA7449 75mm thick plate

Jean-Marie Drezet, Charles-André Gandin, Patrick Schloth

The GP(I) zone formation during quench is simulated in an industrial Aluminumalloy AA7449 75mmthick plate by using a multi-class precipitation model. For this purpose, results of in situ SAXS experiments are reported. A methodology is presented that takes ...

Numerical simulation of AM1 microstructure

Alain Jacot, Charles-André Gandin, Luc Rougier, Paolo Di Napoli

A modelling approach is developed for the description of microstructure formation in the industrial AM1 Ni-base superalloy. Solidification and homogenization simulations are first carried out using a microsegregation model, before using the local compositi ...

Atom probe tomography of secondary gamma ' precipitation in a single crystal Ni-based superalloy after isothermal aging at 1100 degrees C

Alain Jacot, Charles-André Gandin, Luc Rougier

Secondary gamma' precipitation in a commercial single crystal Ni-based superalloy after the 1100 degrees C isothermal aging has been investigated by atom probe tomography. After the isothermal aging for 300 s, 1800 s and 3600 s, a bimodal size distribution ...

Numerical simulation of microstructure formation during solidification and heat treatments of Ni-base superalloys

Alain Jacot, Charles-André Gandin, Luc Rougier, Paolo Di Napoli

A comprehensive modelling approach has been developed for the simulation of microstructure formation during solidification and heat treatment in Ni-base superalloys. The microsegregation taking place during solidification is simulated using the pseudo-fron ...

Probabilistic modelling of microstructure formation in solidification processes

Michel Rappaz, Charles-André Gandin

A new approach to the modelling of grain structure formation in solidification processes is proposed. Based upon a two-dimensional cellular automata technique, the model includes the mechanisms of heterogeneous nucleation and of grain growth. Nucleation oc ...
