“…Studies [46] showed that the indentation size effect could seriously affect the results of nano-indentation measurement. In our previous studies [47,48], we found that, if we first correct the indentation size effect using nano-indentation test data under different loads, then the true hardness, elastic modulus, and yield strength of austenitic stainless steel and titanium alloy can be obtained by the inverse analysis method. The results are in good agreement with the macro mechanical property test results.…”

In this present paper, the mechanical properties of σ-phase and its effect on the mechanical properties of 304H austenitic stainless steel after servicing for about 8 years at 680–720 °C were studied by nano-indentation test, uniaxial tensile test, and impact test. The results showed that the nano-hardness (H), Young’s modulus (E), strain hardening exponent (n), and yield strength (σy) of σ-phase were 14.95 GPa, 263 GPa, 0.78, and 2.42 GPa, respectively. The presence of σ-phase increased the hardness, yield strength, and tensile strength, but greatly reduced the elongation and impact toughness of the material.
