Computations of (ΔσCS + ΔσMS) and Δσorowan as a function of particle size r of γ′ for the CMSX-4 (a) and TMS-138, TMS-196, and TMS-238 superalloys (b), in which the optimal particles sizes (r0) and the experimentally-measured r values, as well as the volume fraction f of γ′ precipitates are also marked for each alloy.
