TENTH PROGRESS REPORT OF THE SHELLY RAIL STUDIES AT THE UNIVERSITY OF ILLINOIS

Repeat cradle type rolling-load tests on two specimens of manganese chrome, vanadium alloy rails gave high cycles for failure 8,117,000 and 9,635,000 indicating that these alloy rails may be several times as good as standard carbon steel rails. A 115-lb. heat-treated standard carbon rail gave 9,625,000 cycles in the cradle rolling machine, which indicates that this type of rail is as good as the manganese, chrome, vanadium alloy rails. Rolling-load tests are reported on high silicon rails, nickel alloy bars and rails, and flame-hardened rails, but none of these particular specimens gave tests comparable with the maganese, chrome, vanadium alloy steel or the heat-treated standard carbon steel rails. Metallographic examination of 14 failed rails which had developed detail fractures in service located rather large inclusions in the steel near the fractures in half of these rails.
