Research on micro-alloyed steel is a strategic measure to meet the needs of various industries and promote green development, and it is essential for many major steel-producing countries. Currently, the mainstream micro-alloying elements in the research and application of micro-alloyed steel are V, Ti, and Nb. Due to the high price of V, the actual production is mostly achieved by adding titanium-niobium composite to change the properties of high-strength steel. This article begins by examining the strengthening mechanisms in titanium-niobium micro-alloyed high-strength steel. It then reviews the literature on how metallurgical processes and second-phase particles affect the steel's properties. The article summarizes the current research status and analyzes the problems in the existing research process and results. Finally, it explores future research directions, offering insights into subsequent studies and applications.
