摘要: Abstract Low temperature can be a significant problem affecting safety and maintenance of railway. In this study, the fatigue crack growth rate rolling contact damage behaviors high-speed rail material under different conditions were investigated by series experiments. The results indicate that stress strength increase with decrease ambient temperature. at 0 °C − 20 °C is similar 20 °C. While, when decreases to − 60 °C, increases sharply. promotion embrittlement low accompanied action high causes rapid failure surface length subsurface damage. Meanwhile, three mechanism models temperatures inferred. brittle fracture mode increasingly apparent decreasing.
