A Novel Design to Eliminate Lüders Band in Medium-Mn Steel and Its Microstructure-Property Relationship

open access: yesCrystals, 2023
In the current work, we design a novel medium Mn steel with a superior mechanical property and no Lüders band. For industrial applications, a “low Mn addition” chemical composition and two kinds of different annealing processes with various initial ...

Stacking Fault Energy in Relation to Hydrogen Environment Embrittlement of Metastable Austenitic Stainless CrNi-Steels

open access: yesMetals, 2021
Metastable austenitic steels react to plastic deformation with a thermally and/or mechanically induced martensitic phase transformation. The martensitic transformation to α’-martensite can take place directly or indirectly via the intermediate stage of ε-

Elevated Temperature Tensile Behavior of a Nb-Mo Microalloyed Medium Mn Alloy under Quasistatic Loads

open access: yesMetals, 2022
The elevated temperature tensile behavior of a Nb-Mo microalloyed medium steel was investigated over the −50 to 150 °C temperature range. The ultimate tensile strength was significantly reduced with increasing deformation temperature, but both YS (yield ...

Influence of Hot Deformation Strain on Austenite Stability in High Nitrogen Martensitic Stainless Steel 30Cr15Mo1N0.37

open access: yesMetals
Hot deformation effectively refines the microstructure and homogenizes the composition of high-nitrogen martensitic stainless steel (HNMSS), but its influence on austenite stability during subsequent cooling remains unclear.

Stabilization of Austenite Associated with Prior Formation of Martensite

open access: yesLe Journal de Physique IV, 1995
The stabilization of retained austenite was studied via a two-step cooling procedure. Alloys with Ms temperatures below 0 °C were used. It was found that the martensitic transformation starting temperature, Ms, was lowered to Ms' during the second step of cooling.
