Read annotation Download PDFThe results of studies on pitting corrosion of 12Cr18Ni10Ti stainless steel austenized after tensile testing at room and low (−20 and −60°C ) temperatures are given. It has been established that local corrosion resistance of cold-deformed stainless steel depends on strain and temperature which determine structure-phase state of material. It is shown that at low degrees of deformation dislocation substructure formed of quasi-homogeneous honeycomb type which has a stabilizing effect on the state of the steel, resulting in increase of resistance to corrosion. Large degree of plastic deformation (>30%) along with the formation processes of high fragmented inhomogeneous structure in 12Cr18Ni10Ti steel initiate phase transformation γ → α΄ to form α΄-martensite, which negatively affects the corrosion resistance of the material.

Read annotation Download PDFLocalized plastic flow in non-irradiated and irradiated with neutrons 12Cr18Ni10Ti stainless steel was investigated using mechanical testing and deformation microcalorimetric method. Mechanisms of necking evolution attributed to γ→α martensitic transformation were identified.
