The last decades have seen a huge growth in the investigation of intermetallic compounds at the interfaces of laminated composites due to their useful features. In this research, effects of the formation of intermetallic compounds on tensile properties and wear resistance of Ni/Ti composites produced by cross-accumulative roll bonding (CARB) process have been examined at different annealing times and temperatures. Scanning electron microscopy (SEM) images demonstrated that the layers were well bonded together, but Ni layers experienced instabilities in light of plastic deformation. The EBSD results showed lamellar structure and crystallographic texture on Ti and Ni layers during plastic deformation. According to X-ray diffractometer (XRD) and energy-dispersive spectrometer (EDS) analyses, NiTi₂ and NiTi were present in all annealed samples. The thickness of intermetallic compounds grew with an increase in annealing temperature and time. However, this growth led to a decrease in tensile strength while the values of elongation fluctuated. Based on the results of the wear test, the composite became more resistant to wear when the thickness of intermetallic layers increased. The surfaces of these layers with less roughness and lower coefficients of friction facilitated the movement of steel pin on samples during the wear test. Furthermore, wear mechanisms of adhesion, abrasion, and delamination were observed, and they were more noticeable at higher loads and lower annealing temperatures and times.

由于其有用的特性，在过去的几十年中，对层合复合材料界面处的金属间化合物的研究有了巨大的增长。在本研究中，研究了在不同退火时间和温度下，金属间化合物的形成对交叉累积轧制 (CARB) 工艺生产的 Ni/Ti 复合材料的拉伸性能和耐磨性的影响。扫描电子显微镜 (SEM) 图像表明这些层很好地结合在一起，但 Ni 层因塑性变形而不稳定。EBSD 结果表明，在塑性变形过程中，Ti 和 Ni 层呈层状结构和晶体织构。根据 X 射线衍射仪 (XRD) 和能谱仪 (EDS) 分析，NiTi ₂和 NiTi 存在于所有退火样品中。随着退火温度和时间的增加，金属间化合物的厚度增加。然而，这种增长导致拉伸强度下降，而伸长率值波动。根据磨损试验的结果，当金属间化合物层的厚度增加时，复合材料变得更耐磨。这些层的表面具有较低的粗糙度和较低的摩擦系数，有助于钢针在磨损测试期间在样品上移动。此外，观察到粘附、磨损和分层的磨损机制，并且它们在更高的负载和更低的退火温度和时间下更加明显。
