Indentation Size Effect during Measuring the Hardness of Materials by Spherical Indenter

Abstract:

The work balance method was used to study the effect of the indenter diameter on the indentation size effect when measuring Brinell hardness. It is shown that the main criterion for the indentation size effect is the specific work of plastic deformation when an indenter is introduced. The conditions of indentation are established to ensure the smallest deviation of the actual hardness value from the true one. The results of the study can be used in determining the mechanical characteristics of materials and in the practice of metal forming processes.
