A review: progress in regulating the ductility loss of graphene-reinforced titanium matrix materials

Graphene nanoplates (GNP) have been found to significantly enhance the strength of titanium and its alloys due to their unique structure and physical properties. However, the use of GNP-strengthened titanium matrix composites is often limited by a loss of ductility, which can hinder their practical application. This article categorizes two approaches to regulate ductility loss: controlling the distribution of GNP in the titanium matrix and optimizing the interface between GNP and titanium matrix. The critical factors in both approaches and the problems to be investigated in depth are also summarized by integrating published research results and related fundamental theories. Controlling the distribution of GNP is a challenging task, particularly in achieving a specific distribution that maintains the ductility of the titanium matrix. The boundary values of the preparation process parameters and the design of new methods are crucial in this regard. To regulate the interface, it is essential to control the degree of interfacial reaction and optimize the interfacial structure. This approach can effectively address the problems of ductility and strength imbalance. Finally, this section summarizes the challenges that must be overcome in order to apply graphene-reinforced titanium-based materials in practical settings.
