摘要：

Surface roughness is an important attribute of fracture surfaces. An assumption-free method for estimation of surface roughness presented in Part I[1] is analyzed further here. It is shown that three vertical sectioning plane orientations mutually at an angle of 120 deg contain sufficient information for a reliable estimation of surface roughness; in most of the cases, the sampling error due to measurements on a limited number (three) of vertical section orientations should be less than ±6 pct with a confidence limit of 95 pct. A simplified procedure is presented for calculation of a profile structure factor from the measurements of the profile frequency function. A practical example of application of the present analysis involving measurement of the fracture surface roughness of a metal-matrix composite is discussed. © 1990 The Metallurgical of Society of AIME.
