The recovery processes of cold deformed Ag and Ag-Ce alloy containing trace cerium were studied by XRD analysis.Based on Scherrer formula and an analytical program,the lattice distortion and subgrain size for both Ag and Ag-Ce alloy were determined in the recovery process.The cold deformed high purity Ag showed tow recrystallization temperature,obvious lattice relaxation and age-softening.The trace Ce solute is an effective inhibitor for recovery softening of high purity Ag since it raises the recrystallization temperature and restrains the lattice relaxation.
