| 摘 要： | 采用爆炸焊接法制备Fe/Al双金属复合管,为表征复合管界面的结合性能进行了压缩、压扁及压剪实验。实验结果表明,复合管结合良好,其界面强度大于纯铝层的抗剪强度,并且能够承受轴向和径向变形。利用扫描电子显微镜观察了原始界面形貌。测试结果表明,结合良好的复合管界面呈波状或直线状。采用液压胀形工艺以Fe/Al双金属复合管制备出复合管正三通,发现良好的界面结合对铁/铝双金属管的塑性成型具有重要作用。

| Abstract: | A Fe/Al clad tube was prepared by explosive welding.Then the bonding characteristic of the interface was investigated by compression,flattening and compression-shear test.The test results exhibit that the clad tubes possessing good bonding interface have higher shear strength than that of pure aluminum and can bear both axial and radial deformation.The original interface between aluminum layer and ferrite layer was observed by scanning electron microscopy(SEM).The results show that the clad tubes with good ... |
