Abstract: In this study, using the newly designed high-entropy alloy TiCoCrFeMn as an example, mathematical models for determining the true hardness from microhardness measurements in the regime dominated by elastic deformation were analyzed. It was found that the PSR model, which accounts for the variability in the elastic component of the applied indenter load, provides the best agreement with macroscopic hardness measurements. Analysis of the load variation law revealed a correlation between the Young's modulus and the Meyer coefficient, which formed the basis for developing a model for determining this material parameter from microhardness measurements. The proposed methodology, applicable to small laboratory specimens, was shown to be consistent with the results obtained from crack-length measurements. [ABSTRACT FROM AUTHOR]
