From the previous studies on recrystallization behavior of precipitation hardening alloys, including our previous papers, it is known that the equilibrium diagrams of the alloys in which fine particles hinder recrystallization, have very small maximum solid solubility.
In the present paper, in order to study the effect of the maximum solid solubility on recrystallization in Cu-base alloys, recrystallization behavior of Cu alloys containing 1 at% each of Zr, Cr, Cd, Ag, Co and Ni were studied by the resistometric method, tensile strength measurements and transmission electron microscopy after quenching and severe cold working. The recrystallization temperatures were obtained by tensile strength measurements.
The experimental results revealed that the recrystallization temperatures were high in the alloys of small maximum solid solubility. A possible explanation of this result is that solute atoms of small solid solubility can exist stably as fine precipitate particles, which hinder dislocation annihilation and grain boundary migration.
