Techniques are developed for determining the spatial and size distributions of spherical inclusions in mild steel. The relations between these distributions as found on electropolished surfaces and as found on fracture surfaces are determined. It is shown that the first neighbor spatial distributions on electropolished surfaces can be described analytically. The average dimple size on a fracture surface is always greater than the most probable first neighbor spacing. The inclusion size distributions both on electropolished and fracture surfaces are shown to be log-normal. The mean inclusion size on a fracture surface is always smaller than that on an electropolished surface. These variations are believed to arise from the nature of the fracture process. |
