  • Relatioship between fracture toughness and mechanical properties of some structural steels at low temperatures
    Ule, Boris ...
    The effect of strain-aging on the impact toughness characteristic of Charpy specimens (CVN) and on quasi-static fracture toughness values K▫$_IC$▫ of some structural steels was investigated in the ... temperature range of nil-ductility temperatures. Strain-aging provokes shifts of Charpy curves to higher temperatures, but it decreases the nil-ductility temperatures regarding to as purchased steels. The correlation between K▫$_IC$▫ and conventional mechanical properties valid for low temperatures confirms that K▫$_IC$▫ and probably also K▫$_arrest$▫ of a strain-aged steels are higher than that of as purchased steels with the same Charpy energy.
