我们对铝包钢在功能材料、钢结构与铝结构焊接结构过渡接头等方面的应用前景抱有很高的期望。本文研究了铝纯度和/或连接条件，如连接温度、铝板厚度变形率、真空度等对真空滚压连接铝包钢抗拉强度的影响。当A1050/SS400复合材料在连接温度高于450°C、Al含量大于17%、真空度小于10Pa时进行拉伸试验时，A1050/SS400复合材料发生断裂。粘接强度均在100 Mpa以上。4N-Al(99.99质量%Al)/SS400复合材料在连接温度为500℃、铝含量为20%、真空度为3Pa时获得了约80 Mpa的粘结拉伸强度，试件通过铝母材断裂。对A1050/SS400覆层材料(粘接温度为500℃，Al含量为20%，真空度为3和10Pa)的粘结界面进行了高分辨透射电子显微镜和电子能谱分析，未观察到金属间化合物和厚度为2~3 nm的连续非晶相。非晶相的成分主要由Al、O、Fe和Si组成。对于4N-Al/SS400复合材料(连接温度为500℃，Al含量为20%，真空度为3pa)的连接界面，用高分辨电子显微镜观察到了非晶相和纳米晶。因此，A1050和4N-Al/SS400真空滚压复合材料是通过非晶相连接的。
We hold many expectations that aluminum-clad steel will be applied for functional material, structural transition joint for welding steel structure to aluminum structure and so on. In this study we investigated the effects of aluminum purity and/or bonding conditions, which were bonding temperature, reduction rate of aluminum plate thickness (RAl), vacuum degree, on bond tensile strength of aluminum-clad steels produced by the vacuum roll bonding. And also the bond interfaces were observed using a high-resolution transmission electron microscope (RE-TEM).When A1050/SS400 clad materials, which produced at more than 450°C in bonding temperature, more than 17% in RAl and less than 10 Pa in vacuum degree, were performed in tensile test, they fractured through base metal of the aluminum. The values of bond tensile strength were obtained over 100 MPa. The bond tensile strength of 4N-Al (99.99 mass%Al) /SS400 clad material, which produced at 500°C in bonding temperature, 20% in RAl and 3 Pa in vacuum degree, was obtained about 80 MPa and test piece fractured through base metal of the aluminum. In the analysis results for bond interface of A1050/SS400 clad materials (500°C in bonding temperature, 20% in RAl and 3 and 10 Pa in vacuum degree) using a HR-TEM and an electron dispersive spectroscopy (EDS), no intermetallic compound and continuously amorphous phase in thickness from 2 to 3 nm were observed. The composition of the amorphous phase consists of mostly Al, O, Fe and Si. For the bonding interface of 4N-Al/SS400 clad material (500°C in bonding temperature, 20% in RAl and 3 Pa in vacuum degree), amorphous phase and nano-crystal were observed using HR-TEM. Therefore, it was clarified A1050 and 4N-Al/SS400 clad materials obtained using a vacuum roll bonding were bonded through the amorphous phase.
