Fe-Ni-Co Alloy Nanopowder

The hot compression of a Fe-Ni-Co alloy was modeled using the finite element method through a commercial package. Incoloy 909 is a superalloy resistant to high-strength precipitation with a relatively constant coefficient of thermal expansion over a wide temperature range and is used in particular for components of aircraft engine shells. Dynamic recrystallization (XRD) during hot isothermal compression was simulated numerically by cellular automata (CA) and finite element analysis. CA models are commonly used to predict the evolution of the microstructure; These models are able to reproduce a series of characteristics commonly observed during XRD. The information of the constitutive behavior of the Incoloy 909 alloy was introduced into the package using experimental data of mechanical tests at different temperatures and strain rates. The results of the simulation coincided quite well with experimentally determined microstructures. Simulation adjustments were made with respect to the experimental results. This research sought to gain a better understanding of the relationship between microstructure and thermomechanical variables.
