Yield Strength

In Thermo‑Calc, a Yield Strength Model is available with the Property Model Calculator and directly calculates yield stress. Yield strength is also available as a variable when working with Plots and Tables that are successors to the Precipitation Calculator. When using the Add-on Precipitation Module (TC-PRISMA), the Yield Strength Model returns the yield strength at room temperature for the specified material using the equilibrium values calculated at temperature T. The Model is defined by further setting the following contributions: intrinsic strength, solid solution strengthening, grain boundary strengthening and precipitation strengthening.
