Study on Surface Brinell Hardness of Cylinder Specimen Based on Indentation Hardness Test
The brinell hardness of non-ferrous metals in planar specimen and cylindrical specimen was measured.The morphology of deformation of indentation was observed and the characteristic parameters were obtained.Contrast the indentation of cylindrical specimen with the one of planar specimen,the representation based on characteristic parameter was set up.The results show that the indentation shape of non-ferrous metal cylindrical specimen is approximate ellipse.The equivalent relation between indentation of cylindrical specimen and indentation of planar specimen is established through measurement of characteristic parameters,and the hardness of cylindrical specimen can be achieved.
