Abstract

Abstract In the present work we study the phase transformation reaction of a Cu-20Zn-7Al (wt.%) alloy by isothermal and nonisothermal 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.
