【Abstract】 In order to provide foundation for reasonable selection of high speed train brake material, the influence of graphite shape on hot fatiage resistant property of cast iron has been studied,resulting in that the best hot fatiage resistant property of cast iron is that of the cast iron with vermiculate graphite,the second is the one with globate graphite while the worst is the one with flake graphite.更多还原
