METHOD OF EVALUATING THE CONTACT STRENGTH OF RAIL STEEL

A method using laboratory equipment for the simulation of the main types of contact damage experienced during rail usage is described. The author states that the use of the method provides data which show the actual relation of contact damage in rails to the carbon content and surface hardness of the steel. The conditions that lead to contact or surface damage of rails are defined in terms of fatigue fracture, variable stresses, types of damage, and fractures caused by rolling and rocking. A description is given of the four-roller machine that is used for contact-fatigue testing and of the various changes that take place within the rail specimen as it is subjected to actions of each roller. Data are included for tests on R50 rails which show extent of rail damage as a function of carbon content of the steel.
