Fracture toughness being represented by the three point bending strength was investigated as a function nitriding parameters and austenitizing temperature. The dominant role of the presence of nitrided layer on both the bending strength and the fracture mechanism was established ? the toughness of the material drops down noticeable when the thickness of nitrided layer increases. The character of the initiation and propagation changes from that of low ? energetic ductile to the cleavage. The effect of other parameters like the austenitizing temperature and thickness of nitrided layer was less significant."@en . "2002-11-26+01:00"^^ . "3"^^ . "0"^^ . "6"^^ . "0"^^ . "Praha" .
