Abstract: Ti-Ni shape memory alloys have been widely used in aerospace, mechanical, electronic, biomedical and other fields due to their excellent shape memory effect and superelasticity, good corrosion resistance and biocompatibility and so on. The interaction between the Ti-Ni matrix and the reinforcements in the Ti-Ni matrix composites can integrate excellent mechanical and functional properties. In the present paper, the latest research progress of Ti-Ni shape memory alloy composites prepared by different methods was reviewed, including the evolution of microstructure, martensitic transformation behaviors, mechanical properties and strain recovery characteristics. In addition, the existing problems and the future development direction of Ti-Ni shape memory alloy composites were analyzed and prospected.
