MEAN FOR IMPROVING RAILS. POSSIBLE WAYS OF IMPROVING THE SERVICE PROPERTIES OF RAILS BY METALLURGICAL MEANS (REPORT OF ENQUIRY)

This report constitutes an analysis of the replies to a questionnaire sent to the Member Railways of ORE concerning possible ways of improving the service properties of rails by metallurgical means. The railways are very interested in these problems and are of the opinion that exhaustive studies seem necessary in the following fields; resistance of steels to brittle fracture and notch effect sensitivity, the influence of residual stresses, and improved ultrasonic inspection techniques for better detection of inclusions. Special attention is also focused on the problem of corrugatory wear.
