This article examines the evaluation techniques of the temperature dependence of frac-
ture toughness with a predetermined boundary. It shows a possibility of their appliance
for the materials used in the manufacture of nuclear reactor vessels.
Keywords:
master curve, basic curve, fracture toughness, fracture probability, brittle
fracture.
