    • Analysis of Requirements and the Feasible Limit for Error Reduction in Two-Parameter Magnetic Determination of Steels’ Hardness 

      Sandomirski, S. G. (БНТУ, 2020)
      All measurements of mechanical properties of materials in the magnetic structural analysis are indirect and relationships between the measured parameters are correlated. An important physical parameter of steel is hardness. An increase in the correlation coefficient R and a reduction in the standard deviation (SD) are achieved when controlling the hardness of steels with two-parameter ...

    • Calculation of Correction Factors for Vickers Hardness Measurements on a Non-Planar Surface 

      Sandomirski, S. G.; Val’ko, A. L.; Rudenko, S. P. (БНТУ, 2022)
      The exact determination of Vickers HV hardness is important for determining of the product material mechanical properties. An important aspect of measuring HV is to obtain its values on a non-planar surface. Regulatory documents contain table values of correction factors K which depend on the surface shape (convex or concave, spherical or cylindrical), its curvature (diameter D) ...
