SUMMARY
The discussion highlights the discrepancies between yield stress obtained from tensile tests and that derived from hardness tests. It establishes that hardness tests are nonlinear and provide only approximate values for yield strength, relying on generalized relationships. This distinction is crucial for material scientists and engineers when selecting appropriate testing methods for accurate yield stress determination.
