摘要
通过室温复合轧制技术成功获得了Ti/Ni/Ti和Ni/Ti/Ni复合材料,利用光学显微镜（OM）、扫描电镜（SEM）、万能试验机等设备对复合材料的界面和显微组织进行观察,并对其力学性能进行测试分析。研究了Ti/Ni/Ti和Ni/Ti/Ni层状复合材料的不同组合方式对界面结合、显微组织和力学性能的影响。研究结果表明：在轧制复合过程中,因组元层的叠层顺序不同,导致其变形行为、组元层厚度和显微组织不同,界面结合形貌不同,力学性能差异较大。通过对比,Ti/Ni/Ti结构的复合材料界面结合状况和力学性能均优于Ni/Ti/Ni。经过90%变形量后,Ti/Ni/Ti的抗拉强度和延伸率分别为：627.67 MPa和12.3%;Ni/Ti/Ni的抗拉强度和延伸率分别为：735.60 MPa和4.8%。
Ti/Ni/Ti and Ni/Ti/Ni composites were obtained successfully with methods of roll bonding.The interface and microstructure of the composites were observed by optical microscope（OM）,scanning electron microscope（SEM）,and its mechanical properties were tested and analyzed by universal testing machine.The effects of different structures on the evolution of interface bonding,microstructure and mechanical properties of the composite plates were investigated.The results showed that the deformation behavior,the component layer thickness and microstructure,the morphology features of interface bonding and mechanical properties were different,because the stacking sequence of the composite material was different in the process of roll bonding.The interface bonding state and the comprehensive mechanical properties of Ti/Ni/Ti were better than that of Ni/Ti/Ni.After 90% rolling reduction,the tensile strength and elongation rate of Ti/Ni/Ti were 627.67 MPa and 12.3% respectively,while the tensile strength and elongation rate of Ni/Ti/Ni were 735.60 MPa and 4.8%,respectively.
