  • Prediction of mechanical properties of Cr-Ni-Mo stainless steel with two-phase microstructure
    Malešević, Milan ; Vojvodič-Tuma, Jelena ; Šuštaršič, Borivoj
    We analyzed results obtained by mechanical tests performed on Cr-Ni-Mo stainless steel, trying to find relation between these results. Primary subject of this analyze were impact toughness results. ... Charpy-V tests were performed on three types of alloys with three different chemical compositions and delta ferrite contents. Alloys were designated as A (2%), B (11%) and C (with 27 wt% of delta ferrite). All results were then described with one suitable function. After that a program for prediction of mechanical properties (impact toughness) was made. Program application was written in Visual Basic 6 environment. With this program is possible to predict a change of impact toughness of Cr-Ni-Mo stainless steel depending on time, working temperature and delta ferrite content of this material, for working temperatures from 290 to 350°C, delta ferrite content from 2 to 27 wt%. To avoid unnecessary mistakes and to focus on time period which have a practical use, time is also limited to 0 to 40 years. We believe that with this same principle used here is also possible to predict mechanical properties of any other material with any other chemical composition. But, this method is pure empirical and this achievement will require much more diverse experimental data.
