抄録

The interdiffusion coefficients in the α-phase of Cu–Al–Zn alloys \ ildeD_ZnZn^Cu, \ ildeD_ZnAl^Cu, \ ildeD_AlAl^Cu and \ ildeD_AlZn^Cu have been determined by an extended Boltzmann-Matano method in a temperature range from 1043 to 1203 K. All of the four interdiffusion coefficients are positive, and they are very sensitive to the solute concentration. The activation energies for the interdiffusion of the ternary alloys are similar to those for the tracer diffusion of Cu–Al and Cu–Zn binary alloys. Large positive interaction parameters ε_Zn^(Al) and ε_Al^(Zn) indicate that Al and Zn atoms in the Cu–Al–Zn alloys have repulsive force between each other.
