摘要：
Compared with Brinell and Rockwell hardness, VICKERS hardness has the advantages of wide measurement range and shallow indentation depth. For metallic materials with homogeneous, continuous, isotropic and power-law hardening characteristics, an elastic-plastic model describing the relationship between VICKERS-indentation load and depth is established by using the energy equivalent method. Combined with the hardness definition equation, the explicit theoretical relationship between the parameters of the material tensile properties and VICKERS hardness is obtained. A new method for integrated VICKERS hardness and tensile properties parameters through the instrumented indentation load depth curve is proposed. Within the range of HOLLOMON model parameters corresponding to the tensile properties of actual materials including steel, copper and aluminum, extensive forward and reverse prediction verification is carried out by using finite element analysis. In addition, the VICKERS hardness test data of nine ductile metal materials in the existing reference are used for integrated prediction and analysis. The results show that the VICKERS hardness and parameters of HOLLOMON model predicted by this method are in good agreement with the results of conventional standard tests. © 2023 Editorial Office of Chinese Journal of Mechanical Engineering.
