The work reports on studies of dynamic strain ageing (DSA) in f.c.c. solid solutions which refer to the problems: (i) mode of diffusion (pipe or lattice) generating the various DSA effects; (ii) the process (saturation or exhaustion) limiting this diffusion; (iii) the current ageing model describing best all results. From experiments on _C_uMn and _C_uAl under precisely chosen conditions an additional enthalpy Δg is derived which phenomenologically describes the DSA effects observed. Its analysis on solute concentration and stress at low and high degrees of tensile deformation yields clear answers to the above questions.
