Modelling of the relation toughness, hardness and tensile properties for two-phase Fe-NiCrMo cast stainless alloys = Modeliranje odvisnosti med žilavostjo, trdoto in raztržnimi lastnostmi pri dvofaznih Fe-NiCrMo litih nerjavnih zlitinah

The effect of the content of [delta]-ferrite in the range of 2 % to 30 % and of ageing for up to 30.000 h in the range from 300 [compositum]C to 400 [compositum]C on mechanical properties was ...investigated for FeNiCrMo alloys. The content of chromium and molybdenum is greater for ferrite and the content of nickel for austenite. Due to the spinodal decomposition of the solid solution during ageing the hardness and the brittleness of ferrite are increased. The mechanical properties were determined at room temperature and at 290 [compositum]C. Due to the spinodal decomposition the average hardness of the alloys increase slightly, while the hardness of [delta]-ferrite is increased faster and much more at the highest ageing temperature. For this reason, after ageing, the mechanical properties are changed; yield stress and tensile strength are increased, while reduction of area, elongation and Charpy toughness are decreased. The effect of ageing time is shown for the investigated alloys for all three ageing temperatures. The change of notch toughness is faster and stronger at higher temperature, and it is greater by testing at room temperature than at testing at elevated temperatures. The initial notch toughness and the toughness after ageing for 17520 h at 350 [compositum]C are shown for all three alloys. The initial and the as aged notch toughness are greatest for the alloy with 2 % of [delta]-ferrite and after ageing notch toughness is decreased significantly for the alloy with 27 % of [delta] ferrite. In all cases notch toughness is greater by testing at 290 [compositum]C than at room temperature, while the effect of testing temperature is opposite for the yield stress and tensile strength. The investigation will be continued with the aim to view the micromorphology of the spinodal decomposition and the development of a model that will relay the change of properties with the content of [elta]-ferrite and the change of notch toughness.
