《Table 1 Material constants in gradient functions of lamellarαmicrostructure in TC17 alloy》
whereεis the strain;T is the deformation temperature(K);is the strain rate(s-1);f1(x),f2(x)and f3(x)are the residuals for the derivatives of the globularized fraction with respect to strain,deformation temperature and lg(strain rate),respectively;X is the globularized fractionare the predicted and experimental derivatives of the globularized fraction with respect to strain at strain i,strain rate j and deformation temperature k;m1 is the number of strain;n1is the number of strain rate;l1 is the number of deformation temperature;wijk is the weight coefficient.Similarly,are the predicted and experimental derivatives of the globularized fraction with respect to deformation temperature at time p,strain rate q and deformation temperature h;m2 is the number of strain;n2 is the number of strain rate;l2 is the number of deformation temperature;wpqhistheweightcoefficient.are the predictedandexperimentalderivativesofthe globularized fraction with respect to lg(strain rate)at time y,strain rate s and deformation temperature z;m3 is the number of strain;n3 is the number of strain rate;l3 is the number of deformation temperature;wysz is the weight coefficient.Finally,the material constants in Eqs.(8)-(10)are listed in Table 1.
