报告摘要：This study attempts to incorporate the effect of elastic deformation in a previously proposed model for the nucleation and growth of precipitates. We adapt the KWN-model by Robson to incorporate the effect of strain energy arising from elastic deformation on the homogeneous nucleation and growth of NbC particles in a High Strength Low Alloy (HSLA) steel at constant temperature. Simulations of the nucleation and growth of NbC particles in an HSLA steel on the cylindrical region show

that the incorporation of elastic strain energies has a noticeable impact on the process. The derived quantities of homogeneous nucleation and growth, such as the particle number density and the mean particle radius, show a clear spatial correlation with the calculated strain energy.
