... that size of cementite decreased as a function of heat treatment cycle. With the increase of heat treatment cycle, the grain size of cementite in all specimens started to decrease. As a consequence, these cementite islands transformed to spherical cementite having an average grain size of 5 μ m...

... crystals along stronger (002) orientation. Surface grain size distribution after the boriding process was identified as an important factor for wear resistance. Different fracture and wear modes were investigated. Analysis of the wear debris gave an insight into the operative wear mechanisms. This research...

... particles and the surface of the cutting tool is most detrimental to tool life. The fatigue wear of the cutting tool is shown to be directly proportional to the silicon content of the alloy, silicon grain size, and to the tool’s loading conditions. Komanduri , R. , McGee , J. , Thompson , R...

... multiple phases to be considered. In this study, the effects of grain orientation distribution, grain size and geometry, as well as the phase distribution and their arrangement, are considered in simulations. Implications of the results are discussed. The influence of microstructure in the surface layer...

... flow theory, with flow factors from Patir and Cheng and Tripp’s use of perturbation. The derived flow factors are obtained as functions of rough surface characteristics, grain size, and collision pattern. As collision energy loss approaches zero, the inelastic results approach those for perfectly...
