dcterms:description
The bainitic steel 15Ch2MFA used for manufacturing of pressure vessel of VVER440 reactor is studied. The microstructure is characterised. The distribution of inclusions and carbides is determined. The quantitative fractography of broken Charpy specimens is carried out. The correlation of crack initiation energy and the area of ductile fracture adjacent to the notch is identified. It is displayed that most of the absorbed energy belongs to the stage preceding the cleavage crack initiation. The influence of irradiation is discused. Je studována bainitická ocel 15Ch2MFA používaná na výrobu tlakových nádob reaktoru VVER440. Charakterizována je mikrostruktura, distribuce inkluzí, karbidů a tvárných důlků. Je provedena kvantitativní fraktografie na Charpyho tělesech. Je určena korelace energie do iniciace nestabilní trhliny a plochy tvárného lomu přilehlé k vrubu. Je ukázáno, že většina energie přísluší tvárnému lomu předcházejícímu iniciaci štěpného lomu. Diskutován je také vliv ozáření na lomovou energii.
