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

Prior Austenite Grain Size Controlled by Precipitates

, 2010
During this study, the correlation between the evolution of the prior austenitic grain size and of the precipitation state during thermal treatment performed on steels is presented. To do this, the precipitation state has been finely characterized. Precipitate volume fractions were measured by plasma spectroscopy. Transmission Electron Microscopy (TEM)

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.

Comparison of Intergranular Corrosion Resistance and Hardness between Nitrogen and Carbon Martensites in Stainless Steels

steel research international, Volume 97, Issue 3, Page 1538-1546, March 2026.
By applying solution heat treatment after plasma nitriding, followed by requenching and tempering, researchers successfully obtained nitrogen‐rich martensite on AISI 409. This study compares the intergranular corrosion resistance and hardness of nitrogen‐rich martensite in AISI 409 with carbon‐rich martensite in AISI 420.

Enabling bainitic transformation acceleration and mechanical properties improvement in ultrafine bainitic steel

Journal of Materials Research and Technology
A novel approach involving the fast heating of cold-rolled pearlite followed by low-temperature isothermal transformation (FBT) was devised to address the technical challenges of long processing times and strength-ductility trade-off in ultrafine ...

Effect of combined V and Ti microalloying on the microstructure and mechanical properties of TRIP-aided bainitic ferrite steel during industrial continuous annealing

Journal of Materials Research and Technology
The industrial production of carbide-free bainitic steels (i.e., TRIP-aided bainitic ferrite steels) plays a crucial role in achieving automotive lightweighting. This study focuses on the isothermal transformation kinetics, microstructural evolution, and

Electrolytic and Chemical Etching : To Reveal Prior Austenite Grain Size (PAGS)

Prior austenite grain size (PAGS) describes the grain structure formed during the high­temperature austenitization that remains after quenching. This microstructure greatly influences mechanical properties such as strength, toughness, and wear resistance.

Effect of Ti and C Contents on Prior Austenite Grain Size in Ti Added Steels

Korean Journal of Materials Research, 2011
Prior austenite grain size plays an important role in the production of high strength hot-rolled steel. This study investigated the effect of Ti and C contents on the precipitates and prior austenite grain size. Steel with no Ti solutes had prior austenite grain size of about 620 .

Tuning heterogeneous microstructure and improving mechanical properties of twin-roll strip cast low carbon steels by on-line heat treatments

Journal of Materials Research and Technology
Coarse austenite grains are unavoidable in the low carbon steels processed by twin-roll strip casting. Unfortunately, the polygonal ferrite (PF) grains cannot be refined by conventional on-line cooling process, resulting in low strength. In this work, an
