  • Simulation of ageing of CF-8M stainless steel
    Malešević, Milan ...
    Results of mechanical tests on CF-8M stainless steels were analyzed to find a correlation between Charpy-V impact toughness (CVN), Vickers hardness (HV5) and tensile strength (Rm) with time and ... temperature of isothermal ageing. These tests were performed on three alloys with different chemical compositions and delta ferrite contents. Alloys were designated as A (2 vol. %), B (11 vol. %) and C (with 27 vol. % of delta ferrite). All results were then described with the most suitable function. After that a computer program for prediction (calculating) of mechanical properties (impact toughness CVN, Vickers hardness HV5 and tensile strength Rm) was made. Program application was written in Visual Basic 6 environment. With this program is possible to predict a change of CVN, HV5 and Rm of CF-8M stainless steels depending on time, aging temperature and delta ferrite content of material, for aging temperatures from 290 to 350 [compositum]C (step 10 [compositum]C), delta ferrite content from 2 to 27 vol. % (step 1 vol. %). To avoid mistakes and to focus on time period of practical importance, the aging time is limited to 40 years. This principle used here allows predicting the mechanical properties of other material additional with any other chemical composition. The confirmation of this requires additional experimental data.
