4A60铝08AL钢层状复合带材冷轧复合工艺及性能的研究中期报告摘要：本报告介绍了4A60铝和08AL钢层状复合带材的冷轧复合工艺和性能研究进展。研究表明，在适宜的轧制条件下，4A60铝和08AL钢之间可以通过冷轧复合得到良好的复合接头，并且接头部位复合均匀、界面清晰。采用扫描电子显微镜（SEM）和能量色散谱分析（EDS）对接头部位进行了组织和成分分析，结果表明：同位异质界面处形成了一层宽度为1-2μm的区域，其中包括4A60铝层和08AL钢层共同形成的FeAl复合层和Fe3Al复合层。接着，对复合带材的拉伸性能和疲劳性能进行了测试，结果表明冷轧复合带材具有较好的拉伸性能和疲劳性能，同时也表明了复合接头区与基材之间的界面强度较高。关键词：4A60铝，08AL钢，层状复合带材，冷轧复合，界面成分，拉伸性能，疲劳性能Abstract：Thisreportintroducestheprogressofresearchonthecoldrollingcompoundprocessandpropertiesof4A60aluminumand08ALsteellaminatedcompositestrips.Thestudyshowsthatundersuitablerollingconditions,4A60aluminumand08ALsteelcanbewell-combinedbycoldrollingandthecompositejointisuniformandtheinterfaceisclear.Thejointwasanalyzedfororganizationandcompositionbyscanningelectronmicroscopy(SEM)andenergydispersivespectroscopy(EDS),andtheresultsshowedthataregionwithawidthof1-2μmwasformedinthesame-heterogeneousinterface,includinganFeAlcompositelayerandanFe3Alcompositelayerformedbythe4A60aluminumlayerand08ALsteellayer.Next,thetensileandfatiguepropertiesofthecompositestripsweretested,andtheresultsshowedthatthecold-rolledcompoundstriphadgoodtensileandfatigueproperties,andalsoshowedthattheinterfacestrengthbetweenthecompositejointandthesubstratewashigh.Keywords：4A60aluminum，08ALsteel，laminatedcompositestrips，coldrollingcompound，interfacecomposition，tensileproperty，fatigueproperty
