Abstract

With the rapid development of China’s rail transit system, technological innovation and industrial application of critical materials have become key factors supporting the safety and economic efficiency of rail transit systems. This article provides an in-depth analysis of technological advancements in critical materials for rail transit, including performance improvements and practical applications of materials for rails, wheels, axles, braking systems, and electrical systems. In the field of rails, the development of nanoscale reinforced rails and weather-resistant rails has significantly enhanced material wear resistance and corrosion resistance, meeting the demands of high-speed and heavy-haul railways. In the wheel and axle sector, the integration of material reinforcement and intelligent technologies has improved operational lifespan and safety. Looking ahead, with further advancements in green manufacturing technologies and smart materials, the greening, intelligence, and sustainability of rail transit materials will become core research and application directions, providing new perspectives for global rail transit technological innovation.
