Effects of Non-metallic Inclusions on Machinability of

Oct 07, 2014 · In Vickers hardness measurement, the hardness of sample AISI1215 not only depends on the chemical composition and microstructure, but also influenced by MnS which is largely existed in steel, the schematic diagram is shown in Figure 17(a). Compared with the matrix of steel, MnS has a lower hardness, which will reduce the Vickers hardness of steel. Evaluation of surface-modified 20CrMo by plasma nitriding Dec 01, 2012 · A much thicker hardened surface layer can be found for sample C:the hardness value exceeds 800 HV within the depth of 110 m, and the hardened layer extends to about 300 m deep when the hardness tends to a saturated ground value. For the 20CrMo steel sample, the increased hardness may be attributed to the grains refinement in the surface layer and the work hardening.
