摘　　要：选用电工纯铁与无氧铜两种组元材料,采用轧制复合工艺制备了Cu-Fe-Cu磁屏叠层材料,对轧合件进行力学性能分析,并运用金相显微镜、扫描电镜、能谱仪等手段分析复合件界面形貌及复合机制。结果表明:采用50%热轧压下率可使铜、铁板有效复合,轧合件内各叠层厚度尺寸稳定、叠层间平行度良好,经简单退火后其叠层间无明显扩散发生,叠层间抗剪切强度达167MPa,此时热轧的主要复合机制为机械啮合。Roll-bonding was used to prepare of Cu-Fe-Cu laminated composite for electromagnetic shielding,oxygen-free copper sheet and electrical iron sheet were chosen as its components.Mechanical property experiments on the laminated composite were executed by using of material testing machine,the microstructure and mechanism of bonding were investigated by means of metalloscope,SEM and EDS.The results show that Cu and Fe can be bonded by hot rolling when reduction rate achieves 50%,thickness deviation and parallelism of each laminates are fine.After the annealing process,it is hard to find the diffusion of Cu and Fe,and the shear strength of interface comes to 167 MPa.The mechanism of bonding by hot rolling is mechanically engage.
