Abstract
Impact tests and internal friction measurements were carried out for steels 40Mn2, 40Mn2Mo and 30CrMnSiNi2. Experimental results showed that the phenomenon of temper brittleness is related to the aging effect of α - solid solution in steels with precipitation of Fe3 (C, N) particles causing dead-pinning of dislocations.
