主　　题：carbon content slack-quenched rail property 

摘      要：A comparative investigation was carried out of the routine mechanical properties,fracture toughness,microstructure and hardness of slack-quenched rails containing different carbon *** the rails slack-quenched,their strength and toughness,together with ductility, are obviously improved,and the higher the quench hardening is,the more the resistance to wear and shell will *** was also made of the reason for this improvement and of the effect of carbon content and quench hardening on the properties of rails in combination with the rail-laying trial.
