<p>The effects of aging treatment on the microstructure and corrosion resistance of cryorolled AA2195 were examined at three distinct aging temperatures: 150, 160, and 170&#xa0;°C. The results indicated that as the aging temperature increased, the average grain size of both room temperature rolled and cryorolled specimens increased by 16%-20%. Under different aging temperatures, cryorolled specimens consistently exhibited superior microstructural characteristics. For instance, at an aging temperature of 160&#xa0;°C, compared to room temperature rolled specimens, the average grain size of cryorolled specimens decreased by approximately 9%, the density of the <i>T</i>₁ phase increased by 9-18%, the width of the precipitated phase chains decreased by about 50%, and the width of the precipitation-free zones decreased by about 20%. Both cryorolled and room-temperature rolled specimens demonstrated a transition in corrosion morphology from intergranular corrosion to pitting as the aging time increased. Under various aging conditions, cryorolled specimens consistently exhibited superior corrosion resistance, with an average corrosion depth that was 6%-16% lower compared to specimens rolled at room temperature under the same aging conditions. Furthermore, their impedance modulus was found to increase by 6%-56% when compared to specimens that were rolled at room temperature under the same aging conditions.</p>
