Influence of carbides morphology on fracture toughness of cast steel G200CrMoNi4-3-3
We analyze the influence of small modification of chemical composition of G200CrMoNi4-3-3 cast steel on the morphology of carbides and on material crack resistance. Using the Termo-Calc software the volume fraction of carbide phase was determined and the results correlated with microstructure observ...

Digital Library of Periodicals of National Academy of Sciences of Ukraine| Резюме: | We analyze the influence of small modification of chemical composition of G200CrMoNi4-3-3 cast steel on the morphology of carbides and on material crack resistance. Using the Termo-Calc software the volume fraction of carbide phase was determined and the results correlated with microstructure observations. Crack resistance of cast steel was determined using SENB specimens and finding critical values of stress intensity factor KQ. Metallographic and fractographic observations of fracture surfaces allowed identifying the mechanism of cracking. |
