Effects of aluminum on hydrogen solubility and diffusion in deformed Fe-Mn alloys [PDF]

, 2016
We discuss hydrogen diffusion and solubility in aluminum alloyed Fe-Mn alloys. The systems of interest are subjected to tetragonal and isotropic deformations. Based on ab initio modelling, we calculate solution energies, then employ Oriani's theory which

Effect of Heat Treatment Parameters on Microstructure, Hardness, and Corrosion Resistance of Martensitic Stainless Steel X30Cr13 (AISI 420B)

Materials and Corrosion, EarlyView.
The hardness and corrosion resistance of the martensitic stainless steel X30Cr13 depend directly on the applied heat treatment. This article describes and discusses the relationships between alloy composition, thermodynamic phase stabilities, heat treatment parameters, resulting microstructures, and achievable corrosion resistance. To investigate these

High-throughput identification of the martensite start temperature in mixed-grain structures

Review of Materials Research
Martensite is a typical microstructure of ultra-high-strength (UHS) steel, with the martensitic start temperature (Ms) being crucial for its mechanical properties. The prior austenite grain size (PAGS) significantly influences Ms, however, establishing a

Experimental and Comparative Study of the Corrosion Behavior of Lean Duplex Stainless Steel in Seawater

Materials and Corrosion, EarlyView.
The localized corrosion behavior of lean duplex stainless steel EN 1.4062 is systematically compared with austenitic and higher‐alloyed duplex grades in natural seawater. A clear resistance ranking is established, highlighting EN 1.4062 as a cost‐effective alternative for limited marine exposure.
