Abstrakt: Various aspects of the master curve methodology have been investigated experimentally based on data obtained with different pressure vessel and container steel. A manganese cast steel has been utilised being considered for storage containers of spent nuclear fuel. Two locations of a segment of container cask, surface and midthickness, have been followed. Some results obtained with the RPV steel of VVER 1000 type and CrMo pressure vessel steel used in petrochemical applications have also been exploited. The applied mechanical testing procedures included: Standard fracture toughness tests at different temperatures using 1T bend specimen in order to determine fracture toughness - temperature diagrams, dynamic fracture toughness has been tested by using hydraulic test machine and drop weight tower. Pre-cracked Charpy specimens have also been tested. For each test technique larger sets of data have been generated in order to follow the statistical aspects. The investigations included procedures of reference temperature determination, both by the one and multitemperature methods, and the evaluation of the scale and constraint effects and the effect of loading rate. For static loading the multi- and single temperature methods of reference temperature determination have been tested with the same family of data. The transferability of results received on the small pre-cracked Charpy specimens was analysed and applied with good results.
