摘要
Rim cracking is the most dangerous failure mode of railway carwheel. The crack is nucleated interior the rim below the tread surface about 5-25mm. In order to prevent the rim cracking, four kinds of steels with different carbon content have been investigated. The mechanical behaviors and microstructures of the steels are analysed.
