Sažetak
The mechanism of ferrite strain ageing is explained in terms of interaction of carbon atoms in solution in ferrite and elastic stresses due to the presence of dislocations. After strain ageing tensile properties are changed to a different extent: yield stress and tensile strength are increased, reduction of area is decreased little and uniform elongation is decreased strongly. The increase of yield stress and the decrease of uniform elongation are smaller for steels with greater as delivered yield stress. Upper and lower shelf notch toughness are affected little, while the notch toughness transition temperature is increased significantly. The change of tensile properties is related mostly to the effect of steel plastic deformation, while the increase of notch toughness transition temperature is explained in terms of synergy of dislocation structure of the plastically deformed steel and interplane segregation of carbon atoms in solid solution in ferrite.
