Journal ArticleDOI
Formation of Shear Bands and Strain-induced Martensite During Plastic Deformation of Metastable Austenitic Stainless Steels
Juho Talonen,Hannu Hänninen +1 more
TL;DR: In this paper, the effects of external stress and stacking fault energies (SFE) on the width of the stacking faults were analyzed and an excellent correlation between the calculations and actual microstructures examined by scanning electron microscopy was found.
Journal ArticleDOI
Effect of strain rate on the strain-induced γ→α'-martensite transformation and mechanical properties of austenitic stainless steels
TL;DR: In this paper, the effect of strain rate on strain-induced γ → α-martensite transformation and mechanical behavior of austenitic stainless steel grades EN 1.4318 (AISI 301LN) and EN1.4301 (A ISI 304) was studied at strain rates ranging between 3×10−4 and 200 s−1.
Journal ArticleDOI
Thermodynamic modeling of the stacking fault energy of austenitic steels
TL;DR: The stacking fault energies (SFE) of 10 austenitic steels were determined in the temperature range 50⩽ T ⩽ 500 K by thermodynamic modeling of the Fe-Cr-Ni-Mn-Al-Si-Cu-C-N system using a modified Olson and Cohen modeling approach as mentioned in this paper.
Journal ArticleDOI
Comparison of different methods for measuring strain induced α-martensite content in austenitic steels
TL;DR: In this paper, the authors compared several techniques for measuring the strain induced α-martensite content in EN 1.4318 (AISI 301LN) and EN1.4301 (A ISI 304) austenitic stainless steels.
Journal ArticleDOI
Highly mobile twinned interface in 10 M modulated Ni–Mn–Ga martensite: Analysis beyond the tetragonal approximation of lattice
Ladislav Straka,Oleg Heczko,Hanuš Seiner,N. Lanska,Jan Drahokoupil,A. Soroka,Sebastian Fähler,Hannu Hänninen,Alexei Sozinov +8 more
TL;DR: In this paper, the authors analyzed the impact of a slight orthorhombic and monoclinic distortion of the Ni 50.2 Mn 28.3 Ga 21.5 at.
