THIRTEENTH PROGRESS REPORT ON SHELLY RAIL STUDIES AT THE UNIVERSITY OF ILLINOIS

One specimen of a chromium-vanadium rail, heat treated to 490 Brinell hardness gave a rolling-load test of 21 million cycles. Ten specimens of high-silicon rails gave rolling-land tests that averaged 2,307,000 cycles. Two specimens of 140-lb. chrome-vanadium alloy rail, gave rolling-load tests that averaged 3,625,000 cycles. One shelling crack started at a segregation streak in the rail. Rolling-load tests to produce detail fractures from shelling indicate that both chrome-vanadium alloy rails and heat-treated carbon-steel rails resist the production of detail fractures better than standard carbon-steel rails. All rolling-load tests to produce shelling indicate that rails with higher hardness, with corresponding increase in mechanical strength, give longer laboratory rolling-load tests.
