Abstract
Abstract The present developments of rail-mounted traffic aim at higher speeds in the passenger and higher axle load in the freight traffic. As a consequence, a substantial increase of the loading of the wheels has to be regarded. Geometric changes at wheels and rails cause high cyclic loading in the dynamic system wheel/rail as a function of the course rate [1– 6]. Since for wheel steels only a few systematic investigations of the fatigue behavior are available so far, the actual investigations concentrate on the relation between the local microstructure and the description of the fatigue behavior of highly stressed wheel steels. As test materials monoblock wheel steels and tire steels were selected in accordance with UIC specification in technically relevant heat treatment conditions. The cyclic deformation behavior is characterized and evaluated by stress – strain hysteresis as well as thermometrical and electrical measurements.
