Aspects of Nitrated Layer Structure for Some Types of Austenite Stainless Steel

The Annals of “Dunarea de Jos” University of Galati. Fascicle IX, Metallurgy and Materials Science, 2006
The analysis of nitrated layer diffractograms and the structure marked out the presence of complex nitrides combinations layer for all types of steel except for code 6 steel type 2CuMoNiCr200 which because of the very high index of austenite stability ...

Positive strain rate dependence: optimizing TRIP effect for high-speed deformation in lean duplex stainless steel

Materials Research Letters
We developed a unique lean duplex stainless steel with a highly unstable austenite phase, exhibiting positive strain rate dependence in tensile properties. Specifically, increased strain rates enhanced the strength-ductility synergy.

Enhancing mechanical properties of medium Mn steel by warm rolling based on laminated elemental segregation

Journal of Materials Research and Technology
The hot-rolled microstructure of medium Mn steel has coarse grains and severe elemental segregation, resulting in low strength and plasticity. Constructing a multiphase structure, refining the microstructure, and regulating elemental segregation enhance ...

Synergistic effects of cryogenic treatment and tempering on mechanical and microstructural properties of M42 HSS

Next Materials
High-speed steel (HSS) tools like M42 must perform well in precision machining applications that require hardness, stability, and wear resistance. The liquid nitrogen cryogenic treatment turns retained austenite into martensite and precipitates fine ...

Stability of retained austenite in TRIP-assisted

, 2008
A theory is developed for the quantitative representation of the strain induced transformation of retained austenite in low alloy, TRIP-assisted steels of the type developed for the automobile industry. It is possible, therefore, to calculate the fraction of austenite as a function of the plastic strain, chemical composition, deformation temperature ...
