| Description
| - Význam práce lze spatřovat v kvantifikaci příčin a charakteristik, které řídí iniciaci interkrystalického křehkého lomu a jeho výskyt v konkurenci se štěpným lomem. Studována byla CrNi ocel komerční čistoty a stejná ocel se zvýšeným obsahem atomů nečistot, Sn a Sb. Interkrystalické zkřehnutí bylo indukováno stupňovitým ochlazováním aplikovaným u obou taveb. Lomová houževnatost byla určována na základě zkoušek tříbodovým ohybem jednak standardních těles a jednak těles typu Charpy s trhlinou. Byla analyzována relace štěpného napětí a kritického napětí pro interkrystalický lom, přičemž byla prokázána vhodnost těchto parametrů pro kvantifikaci kombinace transkrystalického a interkrystalického lomu. Při kvantifikaci morfologických rozdílů v lomových povrchů byla použita fraktální analýza. (cs)
- Main purpose of the work was to quantify causes and characteristics that control the intergranular fracture initiation and occurrence of this fracture micromechanism in competition with cleavage one. A CrNi steel of commercial quality and the same steel with increased content of impurity elements, Sn and Sb, was used. Step cooling treatment was applied in order to induce intergranular embrittlement and brittle fracture initiation in both steel melts. For fracture toughness determination standard bend specimen and pre-cracked Charpy type specimens both tested in three point bending were applied. Relation of cleavage fracture stress and critical stress for intergranular failure has been followed showing capability of this parameter for quantification of the transgranular/intergranular fracture. In order to characterise the quantitative morphological differences in fracture surfaces fractal analysis was applied. (en)
