研究了层合界面的结合强度对多层钢复合材料拉伸变形延展性的影响。制备了由淬火马氏体钢和奥氏体钢交替层组成的多层钢复合材料，其具有各种结合强度，从通过α-氰基丙烯酸酯粘合剂获得的弱结合到通过冷轧和随后的热处理获得的强结合。进行拉伸试验和剥离试验，以研究拉伸行为与界面结合强度之间的关系。结果表明，随着结合强度的增加，拉伸延展性可以显着增强，并且根据界面的结合强度确定了三种类型的拉伸断裂行为。
The effect of the bonding strength of the laminate interface on ductility in the tensile deformation of multilayered steel composites was investigated. Multilayered steel composites consisting of alternating layers of as-quenched martensitic and austenitic steels were prepared with various bonding strengths, ranging from weak bonding obtained by alpha-cyanoacrylate adhesive to strong bonding obtained by cold rolling with a subsequent heat treatment. Tensile tests and peel tests were conducted to investigate the relationship between tensile behavior and bonding strength at the interface. It was demonstrated that tensile ductility could be markedly enhanced as the bonding strength increased, and that three types of tensile fracture behavior were identified depending on the bonding strength of the interface.
