Numerical simulation of precipitation kinetics in multicomponent alloys
Journal of Materials Science and Technology, 2022A universal numerical model based on the particle size distribution (PSD) approach has been developed for the simulation of precipitation kinetics in multicomponent alloys during isothermal ageing. Nucleation was implemented utilizing the classical nucleation theory (CNT).

Modelling Al3Zr dispersoid precipitation in multicomponent aluminium alloys
Materials Science & Engineering A: Structural Materials: Properties, Microstructure and Processing, 2003An integrated modelling approach has been used to predict the precipitation of metastable L12 Al3Zr dispersoids in multicomponent aluminium alloys, during homogenization heat treatment. The Scheil-Gulliver method has been used to predict the segregation of the alloying elements after casting.

Precipitation behavior of uranium in multicomponent solution by oxalic acid
Journal of Radioanalytical and Nuclear Chemistry, 1996A study on the precipitation of uranium by oxalic acid was carried out in a multicomponent solution. The precipitation method is usually applied to the treatment of radioactive waste and the recovery of uranium from a uranium-scrap contaminated with impurities. In these cases, the problem is how to increase the precipitation yield of target element and

Modeling of precipitation kinetics in multicomponent systems: Application to model superalloys
Acta Materialia, 2015A new general model dealing with nucleation, growth and coarsening simultaneously has been developed for the simulation of precipitation in non-dilute multicomponent alloys. Nucleation is implemented using the Zeldovich theory that includes regression effects.

Materials Characterization, 2019
Abstract We investigated the co-precipitation kinetics, microstructural evolution and interfacial segregation in multicomponent nano-precipitated steels strengthened by Cu-rich precipitates (CRPs), NiAl-type particles and Mo2C carbides. Aging hardness evolution of Fe-2Cu, Fe-2Cu-5Ni-3Mn-1.5Al and Fe-2Cu-5Ni-3Mn-1.5Al-1Mo (wt%) steels with elevating ...

Abstract A mathematical model was developed to simulate the precipitation kinetics during heat treatment of multicomponent aluminum alloys. The model is based on the general numerical framework proposed by Kampmann and Wagner, and features a full coupling with CALPHAD software for the evaluation of the Gibbs–Thomson effect.

Precipitation kinetics of complex precipitate in multicomponent systems
Journal of Iron and Steel Research International, 2018A kinetic model based on the classical nucleation and growth theory has been proposed to predict the precipitation behavior of complex precipitate. The method for calculating absolute solution temperature, which is an important guidance for determining solution treatment temperature, is also proposed based on thermodynamic model.
