| Abstract: | A new approach for determining the activation energy of amorphous alloys is developed. Setting the second order differential
coefficient of heterogeneous reaction rate equation of non-isothermal heating as zero at extreme points of DSC curve, we obtain
the new correlation taking form:
|
g1 = Lambertw( g3 e - g2 ) + g2 \gamma_{1} = Lambertw\left( {\gamma_{3} e^{{ - \gamma_{2} }} } \right) + \gamma_{2} |
