Abstract

Magnesium alloys, as lightweight structural materials, have garnered widespread attention in various fields such as aerospace, biomedicine and oil field, presenting immense development potential. Introducing second phases into magnesium alloys is a crucial method to enhance their strength. However, high-strength magnesium alloys often require the addition of high-content alloying elements, leading to large precipitated phase sizes and poor plasticity, severely limiting the secondary processing capabilities of magnesium alloys. It is reasonable to believe that efficiently constructing high-density nano-precipitated phases in the matrix through microstructural control is a significant means to optimize alloy properties. However, this approach still faces certain challenges. Due to their high elastic strain energy, lattice defects serve as preferred sites for the segregation or precipitation of alloying elements. This article, in conjunction with the latest research progress in relevant literature, provides an overview of the effects of lattice defects in magnesium alloys, including twins, dislocations, and stacking faults, on the precipitation of second phases. It discusses the impact of the quantity, morphology, and distribution of precipitated phases on the mechanical properties and corrosion resistance of magnesium alloys. A thorough analysis and summary of these precipitation behaviors contribute to understanding the mechanism of lattice defect-induced second phase precipitation, thereby guiding the regulation of precipitated phases and the development of high-performance magnesium alloys. Finally, addressing the current research challenges in regulating precipitation behaviors in magnesium alloys based on lattice defects, some suggestions and prospects are proposed, aiming to provide references for the further development of high-performance magnesium alloys.
