  • The coefficients of thermal expansion of Cu-Zn alloy between 25~700 ℃, which was before and after 3 GPa high-pressure treatment, were measured by the DIL402C thermal expansion instrument. In addition, the metallurgical microscope, X-ray diffraction (XRD), and differential scanning calorimetry (DSC) were employed to characterize the microstructures and phase transformation of the alloy. Based on the experimental results, the effects of high-pressure treatment on the thermal expansion of Cu-Zn alloy were investigated. The high-pressure treatment can obviously increase the thermal expansivity of Cu-Zn alloy and change the trend of the thermal expansion curve. At 535.14 ℃, the thermal expansion curve after the high-pressure treatment reaches its peak value, which is 49.48% larger than the untreated alloy.
