specimens. The dimensions of the miniaturized specimens used were 3 × 4 × 27 mm (thickness × width ×
length). This specimen type allows utilizing a limited amount of test material or the broken halves of pre-cracked
Charpy or larger specimens. The test material comes from the broken halves of 0.5T SE(B) specimens
previously tested for the determination of the reference temperature at Ciemat, Madrid. The fracture toughness
tests were performed in the transition region of the steel according to the recommendations of the standard
ASTM E1921 and according to Wallin’s recommended temperature range of miniaturized specimens. The
reference temperature of the Master Curve was very similar to the ones obtained from three-point-bend
specimens of sizes 0.2T, 0.4T and 0.5T. The results obtained confirm a necessity to conduct tests at low
temperatures and to test a sufficient number of specimens in order to generate enough valid data for the
determination of the reference temperature.Workplace Institute of Physics of Materials Contact Yvonna Šrámková, sramkova@ipm.cz, Tel.: 532 290 485 Year of Publishing 2018
