Abstract
Using an instrumented microindentation technique for evaluating tensile properties, the present study was undertaken to determine new mechanical parameters measurable in the field that can indicate time-dependent material degradation. Lab-scale tests performed on a Cr-Ni steel and a Cr-Mo steel, two of the most popular heat-resistant steels for facilities in petrochemical and power plants, showed that the work-hardening exponent and yield ratio could be useful as mechanical parameters indicating degradation. The in-field applicability of these parameters was partly verified.
