Abstract The impact toughness, low frequency internal friction and TEM examination were tested for steels 40Mn2, 40Mn2Mo and 30CrMnSiNi2. Experimental results indicate that the appearance of high temperature temper brittleness in these steels seems to be always accompanied by the decrease of Koster peak heights. The mechanism of this phenomenon may be explained as the result of an aging process of α-α-solid solution with precipitation of Fe_3C(N)particles causing pinning of dislocations and thereby decreasing the impact toughness.
