Effect of fine grained ferrite in surface layers on fatigue behavior of low carbon steel plates

Low carbon steel plates with fine grained ferrite in the surface layers produced industrially by a special thermomechanical controlled process have been tested to investigate the effect of ferrite grain refinement on the fatigue behavior of steel plates. Fatigue fractographs were observed and analyzed using a scanning electron microscope. The fatigue properties were obviously improved for the special plates with fine grains in the surface layers.
