摘要
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。
Cu-35Zn alloy was deformed by ten passes constrained groove pressing （CGP） firstly, and then by cold rolling with 10%-30% strain. The microstructure and properties of Cu-35Zn alloy after processed by CGP and cold rolling were studied. The results show that the grains of Cu-35Zn alloy get fined after CGP. The number of deformation twins in the sample increases and the homogeneity of the sample is also improved by subsequent cold rolling. With the increasing of cold rolling strain, the hardness and strength of Cu-35Zn alloy after the deformation of CGP plus cold rolling are increased, but the elongation decreases.
