Multifaceted Behavior and Functional Versatility of Ferritic Stainless Steels, Part I: Applications and Processing, a Review

steel research international, Volume 97, Issue 3, Page 1201-1225, March 2026.
This review investigates the processing‐microstructure‐property relationships in ferritic stainless steels (FSSs). It highlights advances in deformation behavior, heat treatments, surface modifications, and alloying effects. Theoretical models, including Johnson‐Mehl‐Avrami‐Kolmogorov, Arrhenius, nucleation theory, and diffusion theories, are discussed

Minimization of Porosity in E11018‐G Low‐Alloyed Steel Processed by Laser Powder Directed Energy Deposition

steel research international, Volume 97, Issue 3, Page 1369-1383, March 2026.
The processability of the E11018‐G by laser powder directed energy deposition (LP‐DED) is investigated. The effects of powder moisture, ambient humidity, and laser remelting on LP‐DED parts’ porosity are shown. A strong influence of the atomizing gas is observed.

Microstructural Refinement in a Low Alloy High Strength Martensitic Steel

Metallography, Microstructure, and Analysis
Abstract The prior austenite grain (PAG) size of a low alloy high strength martensitic steel, AF9628, was refined by rapid austenitizing heat treatments at 825 and 850 °C. The reduction in PAG size of as high as 97% was obtained. After one rapid austenitizing cycle, the newly nucleated (small) PAGs were observed to be preferentially located ...

Twinned substructure and hardening of low carbon lath martensite by high and atmospheric pressure quenching

Journal of Materials Research and Technology
A low carbon steel (0.2 wt% C) was quenched from 1000 °C under atmospheric quenching (APQ) into water, and under high pressure (HPQ) of 5 GPa at 10 °C/s. Both APQ and HPQ lead to lath martensite with twinned substructure, showing a hardness of 450 HV and
