The state of hydrogen distribution in the steel and the relationship between internal stresses, surface cracking and phase transition is discussed.doi:10.1007/BF00553581P. RozenakMaterials Engineering Department, Ben-Gurion University of the Negev, Beer Sheva, IsraelL. Zevin...
Hydrogen effects on the behaviour of dislocations in austenitic stainless steel The effects of hydrogen and stress (strain) on the phase transitions of a variety of stainless steels (316, 321, 347) were investigated. Hydrogen was introduced by severe cathodic charging at room temperature. X-ray ...
Microstructural Characterization and the Effect of Phase Transformations on Toughness of the UNS S31803 Duplex Stainless Steel Aged Treated at 850 °C Duplex stainless steels, with ferritic-austenitic microstructure, have excellent mechanical properties and corrosion resistance. However, when duplex stain.....
We have performed coupled thermomechanical phase field simulations of martensitic transformation in single-crystalline and polycrystalline 301-stainless steel by coupling Ginzburg–Landau equation to the mechanical equilibrium and non-stationary heat conduction equations. Simulations accounted for elastic anisotropy...
Different austenitic steel powders with additions of Y2O3 and Ti were fabricated by mechanical alloying (MA). The structural evolutions during the process of ball milling and subsequent annealing were studied by XRD, SEM and TEM. Nano crystalline austenitic powders were obtained by MA. Different ODS...
In current study, the effect of microstructure on hot ductility of nickel-free austenitic high nitrogen steel DIN EN 1.4452 was investigated. Phase transformations and precipitation were modeled as well as experimentally determined via microstructural evaluation. Hot tensile and compression tests were used...

We investigated martensitic transformation behaviour in sensitized SUS304 austenitic stainless steel to determine the stability of the austenitic phase at low temperatures. We found that a specimen that was sensitized at 973 K for 100 h exhibits an isothermal martensitic transformation when the specimen ...
The purpose of this study is to find out the effect of surface orientation on the crystallography and morphology of hydrogen-induced surface cracks in an austenitic stainless steel single crystal, in order to have a better understanding of the importance of hydrogen-induced phase transitions in ...
