The microstructure of AISI 304 austenite stainless steel fabricated by the thin strip casting process were investigated using optical microscope, scanning electron microscope (SEM), transmission electron microscope (TEM), and X-ray diffraction (XRD). The microstructures of the casting strips show a ...
AusteniteGrain refinementGrain boundariesEBSDElectron microscopyX-ray diffractionSevere plastic deformation (SPD) was performed on AISI304 stainless steel by surface mechanical attrition treatment (SMAT). The microstructure evolution of the specimens along the depth direction were examined by transmission...
1.10. Microstructure of annealed austenitic stainless steel; the large equiaxed grains are austenite while a small amount of retained delta-ferrite can be seen, particularly at the top left. Each individual grain comprises a unique crystal within the microstructure where the atoms are regularly ordered...
Microstructure of 13Cr super martensitic stainless steels after different heat treatments was studied by means of TEM and XRD.The results show that the microstructure of the steels after quenching is lath martensite matrix.The prior austenite grain size is from 16.8 μm to 56.88 μm for the stee...
The present paper reports an investigation into the microstructural changes occurring in a ferritic–austenitic duplex stainless steel during solution nitriding. Both microstructure and microtexture modifications as a result of nitrogenation have been studied, in addition to the interaction between solution ...

A milling induced deformation layer of Z3CN20.09M, 304L and 316L austenite stainless steel (SS) was investigated by electron backscatter diffraction (EBSD), transmission electron microscopy (TEM) and a nanoindenter. The results indicated that the deformation layer was formed with a depth of about...
The addition of nitrogen in REX734 stabilizes austenite, improves resistance to crevice and pitting corrosion, as well as strength during both monotonic and cyclic loading. Compared to another austenitic stainless steel grade 316L commonly used in implants, REX 734 provides superior corrosion resistance...
also increase the solubility of carbides,nitrides,and carbonitrides in the matrix,and improve the stability of austenite.The results show that the grain size of the material becomes larger with the solution temperature increasing,meanwhile,the mechanical properties are decreased and plastic property is ...
