Simulation of Yield Strength in Allvac^® 718Plus^TM

Abstract:

In the present study, we describe a comprehensive and consistent physical model for the yield strength change in Allvac^® 718Plus^TM caused by precipitation strengthening. The model incorporates the effect of different shearing and non-shearing mechanisms with respect to atomic continuity between the lattices of precipitates and matrix. We demonstrate that coherency and anti-phase boundary effects are the major strengthening mechanisms in this alloy. The final yield strength of Allvac^® 718Plus^TM during aging is investigated using the thermo-kinetic software MatCalc. The calculated final yield strength evolution is consistent with experimental results.
