采用模压形变技术对Cu-35Zn合金进行十道次的模压形变,随后再进行10%～30%不同应变量的冷轧,研究Cu-35Zn合金经复合处理后的微观组织和力学性能。结果表明,Cu-35Zn合金经模压形变后可以细化晶粒,进一步冷轧可以使试样获得更多的孪晶组织;组织均匀性提高。复合处理后材料的强度和硬度随着冷轧应变量的增大而增大,但伸长率下降。
Ten times of compression deformation of Cu-35Zn alloy was carried out by compression molding. Subsequently, the cold-rolling of 10% -30% different strain was carried out to study the microstructure and mechanical properties of Cu-35Zn alloy. The results show that the grains of Cu-35Zn alloy can be refined by the compression deformation, and further cold rolling can obtain more twinned structure of the sample; and the uniformity of the structure is improved. The strength and hardness of the composite material increased with the increase of the amount of cold-rolled strain, but the elongation decreased.
