Investigation of creep properties through sub-size specimen

Popis výsledku v původním jazyce

Residual lifetime estimation and early detection of possible risks of mechanical equipment failure and structures is a key question for reliable operation of industrial plants. Currently, this issue is particularly critical in power stations that are approaching their designed lifetime. Residual lifetime of operating device can be evaluated using standard tests, but these usually cannot be performed due to limited material amount that can be extracted from the components. It is possible to use in these cases a semi destructive sampling of materials and testing methods employing miniature specimens. This article deals with comparison of the creep results obtained with the use of on standard test bars and sub sized samples that are axially loaded. The experiment was performed on steam line steel CSN 15 128 after operation and G17CrMoV510. Emphasis was put to practical use of the test results and therefore residual life was assessed with the use of standard and new mini specimens. The results obtained for standard and mini samples exhibit very good agreement without necessity of any correlation.
