Diffraction and diffusion of X‐rays at high and low temperature have allowed a complete study of order‐disorder transformations of cadmium–magnesium alloys. The equilibrium diagram in the solid state has been established and the transformation mechanisms analysed by examining quantitively the evolution of long‐ and short‐range order parameters for the ordered phase and of short‐range order parameters for the disordered phase. Some observations on the kinetics of transformation may explain certain apparent anomalies of the equilibrium diagram.
