Figure 8. (A) Plot showing average equivalent radius r of the γ’ precipitate versus aging time t during isothermal aging at 750 °C in the 2Cr and 2Mo alloys; (B) Plot between log<r(t)> vs. log(t) in the designed 2Cr and 2Mo alloys during isothermal aging at 750 °C giving the temporal growth exponent of γ’ phases, which corresponds to classical LSW growth exponent; (C) Variation of the average equivalent radius r(t)3 of γ’ phases with the aging time t in the 2Cr and 2Mo alloys where the linear fitting curves are shown, and the fitted slopes corresponding to coarsening rate constant Kr; the coefficient of determination R2 is also marked.
