Abstract

With the development of the steel industry, the application of steel materials in various engineering fields is becoming increasingly widespread. To enhance the performance of steel materials, microalloying technology has gained significant attention. The addition of microalloying elements can effectively improve the mechanical properties, corrosion resistance, and heat treatment performance of steel materials, especially in the production of high-strength steels, where microalloying plays a crucial role. This paper provides a detailed analysis of the mechanisms by which common microalloying elements (such as vanadium, niobium, titanium, and zirconium) affect steel materials, discussing their impacts on grain refinement, phase transformation strengthening, ductility, and toughness. It also explores application examples of microalloying elements in different steel grades. Additionally, the paper discusses the effects of using microalloying elements on steel production processes and environmental protection. Through in-depth research on the mechanisms of microalloying elements, this paper offers theoretical support for optimizing the performance of steel materials and looks forward to their future prospects in the field of steel materials.
