Vpliv pogrevanja na Charpy žilavost martenzita in spodnjega bainita = Effect of reheat temperature on notch toughness of martensite and lower bainiteKosec, Gorazd ...V sodobnih visokotrdnih konstrukcijkih jeklih se zmanjšuje količina ogljika zato, da se zmanjša možnost nastanka martenzita v področju cone toplotnega vpliva (CTV), kjer avstenitna zrna najbolj ... zrastejo. S tem se doseže, da pred varjenjem jekla ni potrebno predgreti in tako zmanjšati hitrost ohlajanja zvara pod tisto, pri kateri nastane martenzit, ampak avstenit premeni s procesom, katerega naravo določa difuzija ogljika. Dosedanje raziskave so pokazale, da je žilavost v CTV po varjenju sicer večja, če ni premene v martenzit, ampak v spodnji bainit, vendar pa se po pogrevanju, s katerim se simulira segrevanje prejšnjega varka po depoziciji naslednjega, žilavost spodnjega bainita zmanjšuje mnogo bolj, kot žilavost martenzita.Source: Program in knjiga povzetkov = Program and book of abstracts (Str. 44/KM-MR)Type of material - conference contributionPublish date - 2006Language - slovenian, englishCOBISS.SI-ID - 596138
