| Description
| - The specific desired properties for structures and components working in critical environments (e.g. pressure vessel of nuclear power plant) require current information about degradation processes coming out in materials. This information is essential and inevitable input for residual lifetime assessment. Possibility of the classical (standard) mechanical testing (tensile test, Charpy test, fracture toughness test, creep test etc.) is very limited, because there is not sufficiently of material to be non-invasively taken from the component. Sampling material from in-service structures and components is very complicated and time consuming, and in addition to that the component has to be repaired after this extraction. Hence, the new innovative techniques based on miniaturized specimens have been developed for evaluation of mechanical properties and their changes. One of very promising techniques is Small Punch Test. This test can be considered as non-destructive method – test sample is disc 0.5 mm thick and 8 mm diameter. Even if this test evaluates relatively small volume of material we can use it for investigation and description of degradation processes of the whole components. Present paper summarizes the results obtained for specimens of steel 15Ch2MFA with different heat treatment and for specimens of steel O8Ch18NT10 with various degree of deformation. Fractographic analysis was carried out in order to describe failure processes taking place in material during Small Punch Test. Obtained information was used to justify the correct test procedure.
