Abstract

The relationship between micro Vickers hardness and indentation hardness of GCr15 and 9CrSi materials under different test forces is studied, and the corresponding formulas are given. This not only makes it easy to get the unknown information of the two materials under any limited test conditions, but also provides a direction for exploring the property change of other materials in the whole test process and related researches. The experimental results are compared with the equations given by the finite element method, which provides a powerful reference for the further improvement of the theoretical analysis.
