Abstract

Abstract In the present work we study the phase transformation reaction of a Cu-20Zn-7Al (wt.%) alloy by isothermal and non-isothermal in situ X-ray diffraction. An effective activation energy for each phase is obtained for the range between 275 and 395°C. The experimental data are also adjusted with the JMA equations. Finally, we present the TTT (time–temperature–transformation) diagram corresponding to the precipitation of alpha and gamma for the lower temperatures. Below 340°C, we found for this alloy that the gamma phase precedes the formation of alpha.
