摘要

A new type of Nb-V-Ti microalloyed cast steel was produced. Computer simulation was adopted to optimize the content of alloying elements. The microstructure of the microalloyed steel was analyzed. The fatigue property, wear and friction properties and rupture toughness of the steel were investigated. The service and operating properties of Nb-V-Ti microalloyed cast steel coupler were also examined. The results show that the steel has excellent comprehensive mechanical properties. The granular bainite structure and precipitation strengthening are the primary strengthening mechanism. The fine grain brings the steel good plasticity and excellent toughness. Various service and operating properties of Nb-V-Ti microalloyed cast steel automatic coupler are excellent.
