Effect of initial structure and cold deformation on the stress - elongation curve of duplex stainless steel (α + γ) in a static tensile testing at 850°C

Prace Instytutu Metalurgii Żelaza > 2018 > T. 70, nr 4 > 34--38

The results presented in the article concern the effect of structure and cold deformation on the behaviour of a highalloy duplex stainless steel (α + γ), grade X2CrNiMoN22-5-3, in tensile tests at 850°C at a rate vr= 15·10-3mm/s. Tests were carried out for a sheet after supersaturation from 1250 and 1350°C and subsequent cold rolling with the values of εhdeformation within the range of 0.5÷0.9. It...

Struktura wlewków ciągłych ze stali niestopowych i niskostopowych oraz jej ewolucja w wyniku przeróbki plastycznej na gorąco

B. Garbarz

Prace Instytutu Metalurgii Żelaza > 2018 > T. 70, nr 4 > 2--23

W artykule przedstawiono systematykę morfologiczną struktur powstających we wlewkach ciągłych ze stali niestopowych i niskostopowych. Scharakteryzowano pierwotną strukturę krzepnięcia (strukturę dendrytyczną) oraz ziarnową strukturę austenitu pierwotnego. W zależności od składu chemicznego stali, warunków krzepnięcia i stygnięcia wlewka ciągłego oraz od zastosowanych metod ujawniania elementów morfologicznych,...

Prace Instytutu Metalurgii Żelaza > 2018 > T. 70, nr 4 > 24--33

JMAK (Johnson-Mehl-Avrami-Kolmogorov) equation was adapted to simulation of phase transformations during cooling of bainitic steel tubes. The model was identified on the basis of the results obtained from the JMatPro software. Numerical tests for various cooling schedules showed model’s capability to predict a volume fraction of microstructure constituents of the tubes. The model was implemented into...
