Description/Abstract

The kinetics of beta prime formation from supersaturated Al-15mass%Mg solid solutions was studied by micro-calorimetry and transmission electron microscopy (TEM). It is shown that the transformation can not be described by the commonly used equation: d alfa / dt = f(alfa) k(T). The function f(alfa) is different at different temperatures. Apparent activation energies decrease with amount transformed from 1.07 eV to 0.7 eV. These findings are discussed in terms of overlapping of the nucleation and growth processes for beta prime.
