Fig. 20 Comparison of residual stresses in carburized versus through-hardened steel races. The higher residual compression of carburizing M50-NiL provides greater resistance to fracture, fatigue damage, and stress corrosion. Source: Ref 11 More

Fig. 9 Hardened steel bushing characteristics (stroke length, 25 mm, or 1 in.) More

Fig. 5 Microetch coupon of a case-hardened steel with Knoop microindentation hardness profile. This section allows mesoscale evaluation of structure, in this case, variation of case depth. More

Fig. 17 Induction-hardened steel bar macroetched to show spiral band of prequenched material More

Fig. 21 Grinding temperature cycles in different depths in the hardened steel. Source: Ref 24 More

Fig. 22 Maximum temperature drop as a function of depth in the hardened steel at various work speed ( V w ). Source: Ref. 24 More

Fig. 19 Setup for end lapping large quantities of hardened steel rollers More

Fig. 64 Example of a line spall in a forged, hardened steel roll. (a) Section containing the spall cut from the roll. The arrow indicates the origin of the fracture, about 6 mm (0.25 in.) below the roll surface. (b) The fracture origin at 6.5×. Fatigue beach marks originate at the arrow; gross More

Fig. 23 Subsurface residual-stress distribution after grinding hardened steel (stress measured in the direction of grinding). Source: Ref 3 More

Fig. 6 Fracture surface of a carburized and hardened steel roller. As a result of banded alloy segregation, circumferential fatigue fracture initiated at a subsurface origin near the case-core interface (arrow). More

Fig. 8 Unetched metallographic cross section through hardened steel roller test specimen with sliding plus rolling contact (sliding to left and rolling to right). Fatigue cracks initiate at surface. Source: Ref 11 More

Fig. 19 Oblique view of a 102 mm (4 in.) diameter hardened-steel machine rod that failed by fatigue fracture. Curved beach marks identify two distinct fracture origins, separated by a step of overload fracture (light gray). Older parts of fatigue fracture are decorated by corrosion product More

Fig. 36 Fracture surface of a hardened steel connecting rod. Arrows indicate large inclusions. Fatigue cracking initiated from the middle inclusion. More

Fig. 37 Fracture surface of a hardened steel valve spring that failed in torsional fatigue. Arrow indicates fracture origin at a subsurface nonmetallic inclusion. More

Fig. 38 Fracture surface of a carburized-and-hardened steel roller. As a result of banded alloy segregation, circumferential fatigue fracture initiated at a subsurface origin near the case/core interface (arrow). More
