The new comprehensive phenomenological modeling, which is based on the concept of dislocation-<I>nucleation</I>, -<I>multiplication</I> through various interactions with the obstacles and -<I>annihilation</I>, has been applied to precisely describe the tensile behavior of a precipitated FCC alloy system. The alloy has been subjected to isothermal aging treatment for different durations in order to develop various microstructural conditions comprising precipitates of progressive sizes. Statistical physical parameters extracted using the modeling of individual tensile plot are seen to be in consonance with the idea of fixed- and dynamic- mean-free-path (MFP) of dislocation obstacle interaction. These parameters from the tensile plot of individual aging condition have been modeled further to predict the plastic flow curve for any arbitrary isothermal aging duration.
