Abstract: In this work, we have studied the precipitate growth behavior of a metal matrix when subjected to hydrostatic pressure. We utilized Zenner-Frank phase field kinetics with integrated free energy density functional based on volumetric strain energy. We studied the precipitate growth up to 2 GPa under varying bulk modulus of the precipitate phase. We observed that subjecting to hydrostatic pressure influences the growth kinetics by reducing the precipitate growth under time evolution. In addition, the bulk modulus of the precipitate has shown an abnormality in the growth behavior compared to general observations under hydrostatic pressure. This work contributes to the smart tailoring of novel materials to reduce detrimental impacts on holistic material properties, used in large hydrostatic pressure applications.
