Abstract
The conventional test methods combined with non-standard measuring of fracture toughness Kic for the determination of low- temperature limit of exploitation was applied on nine different structural steels either fine-grained micro- alloyed steels or low-alloyed structural steels. These experiments confirmed that the results of low-temperature tests could be succesfully used for the calculation of some fracture mechanics characteristics of the investigated steels as for instance the dynamics yield strenght [MATH], the dynamics fracture toughness Kid and, of course, the static fracture toughness Kic.
