Development of new materials is connected with the limited amount of test material available. In those cases characterization of mechanical properties or fracture behaviour of the materials requires an application of miniaturized test specimens. It can be a miniaturized variant of commonly used test specimen or an optimised geometry for the requited need. Such specimens usually have their dimensions in the order of millimetres. Testing, evaluation and interpretation of the obtained data from miniaturized specimens require suitable force range and strain measurement. Moreover an optimised procedure of interpretation of the obtained results is needed especially when the measured characteristics is beyond the limits specified in the standard. The contribution describes the experience with testing and fracture behaviour description both miniature tensile and fracture toughness specimens obtained on advanced steels (Eurofer97 steel, JRQ steel, ODS steels) at IPM.
