Effect of Two-Step Aging on the Microstructure and Mechanical Properties of Cu-2.7Be Alloys

Abstract:

The effects of two-step aging on the microstructure and mechanical properties of Cu-2.7Be alloys were investigated in the present study, compared with one-step aging. After cold rolling the Cu-2.7Be alloys were heated by different combinations of temperature and time. The results revealed that two-step aging could obviously increase the strength of Cu-Be sheets when the aging temperature was 380 °C. At the temperature of 320 °C and 340 °C, there was no distinctly difference of strength and elongation between two-step aging and one-step aging. The SEM of fracture surfaces showed that the number of dimples increased with the increase of aging temperature.
