• This paper provides a comprehensive review of the preparation methods and mechanical properties of Ti-reinforced magnesium matrix composites (MMCs), offering insights into their application in aerospace, automotive, and electronics industries. • The deformation incompatibility between Ti and Mg phases and its role in inducing strain gradients at the interface are analyzed, highlighting the importance of geometrically necessary dislocations (GNDs) in enhancing strain hardening and ductility. • The influence of interfacial products, second-phase size, texture, and grain size on the mechanical, and physical properties of Ti-Mg composites is systematically discussed. • The challenges in developing micromechanical models that resolve the coupled plasticity of Ti and Mg phases are emphasized, along with the need for optimizing interfacial bonding strength and morphology. Magnesium matrix composites (MMCs) combine exceptional low density, high specific strength, and stiffness, positioning them as critical materials for aerospace, automotive, and electronics industries. This review highlights recent progress in the fabrication of Ti-Mg composites and analyzes the mechanisms behind their enhanced mechanical properties. A key focus is the interfacial deformation incompatibility between Ti and Mg phases, which generates strain gradients and promotes the accumulation of geometrically necessary dislocations (GNDs) at the interface. This process not only improves strain hardening and duc...
