摘　　要：基于实际生产线,研究添加DT4或SL3夹层材料对TA2/Q235B复合板组织及性能的影响。通过金相显微镜(OM)、扫描电镜(SEM)、能谱电子衍射(EDS)、X射线衍射(XRD)和力学试验等对钛/钢复合板进行分析。研究发现,添加DT4夹层的复合板界面较为干净,TiC较为均匀,界面化合物等相对较少,剪切强度达到187.4 MPa;添加SL3夹层的复合板界面夹杂物较多,界面存在TiFe、TiNi等金属间化合物,剪切强度仅为148.6 MPa。两种夹层的复合板剪切断裂位置均发生在钛侧,断口处均发现脆性断裂特征。研究表明,加入DT4夹层复合板的剪切强度更高,有利于工业化生产。The effects of adding DT4 or SL3 sandwich materials on the microstructure and properties of the TA2/Q235B composite plate are studied based on the actual production line.The mechanical properties and microstructure of the TA2/Q235B clad plate are analyzed through metallography(OM),scanning electron microscope(SEM),energy disperse spectrum(EDS),X-ray diffraction(XRD) and mechanical tests.According to the study,the clad plates containing DT4 interlayer has clean interface,less compound,and uniform TiC,and its shear strength is up to 187.4 MPa.As for the clad plate with SL3 interlayer,there is more slag inclusion in the interface,where TiFe,TiNi and other compounds can be found,and the shear strength is only 148.6 MPa.The shear fracture locations of the composite plates of the two sandwiches occur on the titanium side,and the brittle fracture features are found in the fracture.The results show that the shear strength of the DT4 sandwich clad plate is higher,which is conducive to the industrial production.
