摘　　要：Ti/Cu/Ti laminated composites were fabricated by corrugated rolling(CR) and flat rolling(FR) method.Microstructure and mechanical properties of CR and FR laminated composites were investigated by scanning electron microscopy, numerical simulation methods, peel and tensile examinations. The effect of CR and FR was comparatively analyzed. The results showed that the CR and FR laminated composites exhibited different effective plastic strain distributions of the Ti layer and Cu layer at the interface. The recrystallization texture, prismatic texture and pyramidal texture were developed in the Ti layer by CR, while the R-Goss texture and shear texture were developed in the Cu layer by CR. The typical deformation texture components were developed in the Ti layer and Cu layer of FR laminated composites. The CR laminated composites had higher bond strength, tensile strength and ductility.采用波纹辊和平辊轧制方法制备钛/铜/钛(Ti/Cu/Ti)层压复合板材料。通过扫描电镜、数值模拟、剥离和拉伸实验等方法研究层压复合板的显微组织和力学性能,对比分析波纹辊和平辊轧制效果。结果表明:波纹辊和平辊轧制的层压复合板在Ti层和Cu层界面处表现出不同的有效塑性应变分布。波纹辊轧制的层压复合板中,Ti层具有再结晶织构、棱柱面织构和棱锥面织构,Cu层形成高斯织构和剪切织构;而平辊轧制的层压复合板中,Ti层和Cu层均具有典型的变形织构。波纹辊轧制的层压复合板材料具有较高的结合强度、抗拉强度和延展性。
