A liquid metal embrittlement specificity of three austenitic steels with increasing nickel content (304L, 316L and 316L(N)) is studied in mercury. Only the low alloys are susceptible to LME. The crack path an steel fracture induced by mercury has been elucidated. Deformation martensite (γ → α’) induces numerous α’/α’ interfaces at small scale that be embrittled. Because only resists LME one sho...

The formation of a protective chromium carbide passive film makes austenitic stainless steel (ASS) alloys suitable for corrosive and high-temperature environments. This paper examined the transformation microstructure, corrosion, mechanical properties gas tungsten arc welded 316 steel. scientific principles governing metallurgical corrosion dynamics were discussed. review shows that on 316L ASS...

Hydrogen gas has been widely recognized as an environmentally clean and renewable energy fuel, and it provides a way to reduce greenhouse gas and air pollution emission. A great deal of effort has been made to develop new techniques in the field of hydrogen energy, including hydrogen production, storage, and infrastructure. Recently a metallic gasket, which is made of type 316L stainless steel,...

The plastic co-deformation behavior at the homophase interfaces between the hard nanotwinned grain inclusions and the soft recrystallized matrix grains in a duplex-microstructured AISI 316L austenitic stainless steel is examined through the analysis of long-range orientation gradients within the matrix grains by electron backscatter diffraction and transmission electron microcopy. Our analysis ...

In industrial rolling, changes in strain rate and temperature occur with strain during passes, and between one pass and the next. Plane strain compression testing has been used with ramped changes in strain rate during deformation, and with changes in strain rate between two deformations to study their effects on flow stress. No systematic deviations from a mechanical equation of state were fou...

A split Hopkinson pressure bar is used to investigate the dynamic mechanical properties of biomedical 316L stainless steel under strain rates ranging from 1 × 10(3) s(-1) to 5 × 10(3) s(-1) and temperatures between 25°C and 800°C. The results indicate that the flow stress, work-hardening rate, strain rate sensitivity, and thermal activation energy are all significantly dependent on the strain, ...

A surface hardening technique called “interstitial hardening” has been developed to introduce interstitial carbon atoms into stainless steel surfaces without the formation of carbides. Surface hardening of machine elements such as impellors or fasteners would improve performance regarding cavitation and galling resistance, and has intensified interest in this process. The interstitial hardening...
