| Description: |
AbstractAdvanced high-strength (AHS) steels containing aluminium, manganese, silicon and carbon have widely been studied for automotive applications. It is particularly important to know their solidification behaviour and final structure after the austenite decomposition process. A thermodynamic database named the Iron Alloy Database (IAD) has been developed to provide consistent thermodynamic data for the purpose of simulating the solidification of steels. This work presents a thermodynamic assessment of the Fe–Al–Mn–Si–C system and 19 subsystems. The results suggest a good agreement between thermodynamic descriptions and the measured data. see all
TiivistelmäAlumiinia, mangaania, piitä ja hiiltä sisältäviä kehittyneitä suurlujuusteräksiä on tutkittu runsaasti autoteollisuuden sovelluskohteiden näkökulmasta. Erityisen mielenkiinnon kohteena on niiden jähmettyminen ja lopullinen rakenne austeniitin hajoamisprosessin jälkeen. Termodynaaminen Iron Alloys Database (IAD) –tietokanta on kehitetty tuottamaan konsistenttia termodynaamista dataa terästen jähmettymisen simulointiin. Tämä työ esittelee Fe–Al–Mn–Si–C –systeemin ja 19 alisysteemin termodynaamisen arvioinnin. Tulokset osoittavat, että termodynaamiset kuvaukset vastaavat mitattua aineistoa. see all
