“…Consistent with this study, previous investi~ators 2 ' 4 • 6 have suggested that•steel containing martensite .or bainite (and we emphasize it would be lower bainite) are preferable to ferritic or pearlitic microstructures for resisting wear. This conclusion is further supported by two body abrasive wear tests for which the fine-grained 2% Mn experime~tal steel was observed to be the most wear resistant, followed by Abrasalloy (Figure 13).…”

“…There are contradictory opinions in the reported literature -some authors [22][23][24][25] suggested that increase in hardness increases abrasive wear resistance, while few others reported 26,27) a decrease in abrasive wear resistance with the increase in hardness, in particular, where abrasive wear by brittle fractures predominates. Relatively less data is published regarding the abrasive wear behaviour of En31 steel.…”

Ni-Cr-Mo steels are widely used in machine part members, gears and shafts. Steels with higher carbon content (~1%) are used for heavy machine parts and bearings. Abrasive wear resistance is often a very important requirement for these high carbon steels, apart from sliding wear properties. In the present study, En31 steel was subjected to varying heat treatments to generate different microstructures. An attempt has been made to correlate the two body abrasive wear resistance with the bulk hardness and microstructures. The microstructures were studied through a combination of scanning electron microscopy (SEM), energy dispersive spectrometer attached to SEM (i.e. SEM-EDS) and X-ray diffraction (XRD). The bulk hardness decreased with increase in tempering temperature from 423 K to 848 K. The precipitation of Cr7C3 after 598 K tempering did not cause an appreciable increase in the hardness. At higher tempering temperatures (848 K), the martensite decomposed to give ferrite and cementite. The abrasive wear tests were carried out on hardened and tempered specimens. The abrasive wear mass loss increased with increase in the tempering temperature. Hardness had a direct correlation with the two body abrasive wear behaviour in En31 steel -increase in hardness increased the abrasive wear resistance. The important material removal mechanism were micro cutting and micro ploughing, the relative contribution of each to total wear loss was influenced by abrasive wear test conditions.

“…For example, the wear resistance and hardness increase as the fraction of pearlite in a mixture with ferrite, becomes larger [22]. It is difficult to make comparisons because of experimental data are differently derived, but the variation in abrasive-wear rate seems greater when the pearlite fraction is changed by altering the carbon concentration of the steel [22][23][24], as opposed to when it is altered by changing the heat treatment for the same steel [25]. Nevertheless, the fact that in the present work, large variations in hardness do not lead to large differences in wear rate is inconsistent with published three-body tests reported on 4340 steel where about a 40% improvement was achieved in three-body abrasive wear resistance for a hardness increase of 325 kgf-mm −2 [26].…”

The abrasive wear of three metallurgical structures with radically different hardnesses have been investigated for the same steel. The particular steel concerned is a recent innovation capable of generating extremely fine distributions of crystals. The austenite in the alloy nevertheless has the capability of uniformly transforming into extremely fine pearlite, nanostructured bainite, and plate martensite. It is found that although the abrasion rates and wear coefficients are not very different for the three states, the mechanisms of abrasion are quite different. We report detailed characterisation experiments together with comparisons with commercially available steels subjected to identical tests.
