Abstract
The mechanical behavior of carbon case-hardened components is approached in a systematic manner. Carburized components are viewed as composites of high carbon and low carbon steels. Simulated case and simulated core materials are evaluated separately in homogeneous specimens to determine the independent contributions of each to the overall mechanical behavior. Strain-controlled axial fatigue tests are used to characterize the cyclic deformation and fatigue behavior of case, core and carburized material specimens. The results of these tests are used to correlate the responses of the separate case and core materials to the total mechanical behavior of carburized steel.
