The compositions and phase structures and micro-hardness of the coating and the heat affected zone(HAZ) were researched by means of optical microscope, scanning electron microscopy(SEM), x-ray diffraction (XRD) ,electron probe microanalysis(EPMA) and micro-hardness tester.Analysis and discussion to...
The hardness was measured by a Vickers hardness tester with a load of 30 kg. The sample for the uniaxial compression test was made into a cylindrical shape with the dimensions of ϕ6 mm × 9 mm. The strain rate and the maximum compressive stain were set to be 0.005 s−1 and 10%,...

FIG. 2 is a schematic, largely cross-sectional view of the lapping arrangement of FIG. 1, used to condition a multiple-phase or composite working surface having phases of varying degree of hardness; FIG. 3 is a schematic, cross-sectional view of a multiple-phase or composite workpiece lapped...
hardness of 4.2 GPa, which is lower than the hardness of the BCC Fe84Ni16sample and is thus not supposed to act as a reinforcement. In order to experimentally substantiate the proposed GB-mediated transformation strengthening pathway, we prepared a nanograined Pd-Au alloy withd = 19.2...
When approximately 30 seconds had elapsed, a further 50 milliliter sample was applied to the sponge (water dampened, then wrung to remove excess water) of a Gardner Abrasion Tester apparatus. Thereafter the apparatus was cycled 10 times, which provided 20 strokes of the sponge across the face ...
was synthesized by our group14. This nanocrystalline WC-Co cemented carbide bulk possesses a superior combination of hardness and fracture toughness. By using Vickers hardness tester and indentation method, the hardness and fracture toughness were measured asHV = 2050 ± 10 kg fmm−2...
However, the distribution of the re-aged precipitates is more dense and the size is smaller than that of the first-aged precipitates, and the increase in the hardness of the alloy after re-aging is mainly due to the strengthening of these fine and dense δ-(Ni, Co) _2Si precipitated ...
