Kinetics of phase transformations in Cu-Al and Cu-Zn-Al alloys

Abstract

The non-isothermal kinetics of the solid-state reactions taking place in Cu-AI and Cu-Zn-AI alloys were studied by DTA and X-ray measurements. It was found that the degree of conversion, which represents the change in the reacting system; is a function of the area increase in the DTA peak. The kinetic analysis shows that DTA is a useful method for the study of formal kinetic laws. From the f(~) functions, conclusions on the mechanism of the phase transformations can be drawn.
