Thermomechanical and Microstructural Analysis of the Influence of B- and Ti-Content on the Hot Ductility Behavior of Microalloyed Steels

Metals, 2022
The effects of the combined addition of B and Ti, as well as the influence of different strain rates on the hot ductility behavior of low carbon, continuously cast, microalloyed steels were investigated in this work.

Reducing the use of Fossil Carbon and Fuels to Defossilize the Electric Steelmaking Route: Evaluation of the Effects of Alternative C‐Bearing Materials and Hydrogen in the Electric Arc Furnace

steel research international, EarlyView.
The experiments and simulations demonstrate that, in general, alternative carbon sources can decrease fossil CO2 without adversely impacting EAF process and product. High plastics and tires ratios cause unsafe conditions and poor slag foaming. Hydrogen in EAF burners decreases CO2 but increases water vapor, which can raise the hydrogen content in ...

Influence of Oxygen Contamination on the Genesis of Nonmetallic Inclusions in a Microalloyed Steel

steel research international, EarlyView.
Oxygen contamination during melting of steels strongly affects the evolution of nonmetallic inclusions. Controlled remelting experiments, combined with SEM/EDS analysis and thermodynamic simulations, reveal how reoxidation promotes the transformation of alumina‐based inclusions into complex FeO–MnO oxides and other interactions.

A Review on Cracking in Laser Additive Manufacturing of Nickel‐Based Superalloys: Types, Formation Mechanisms, and Suppression Strategies

Rare Metals, Volume 45, Issue 4, April 2026.
ABSTRACT Nickel‐based superalloys (Ni‐based superalloys) have attracted extensive attention in laser additive manufacturing (LAM) due to their capability to directly fabricate complex and high‐performance structural components. However, the rapid melting and solidification inherent to LAM result in intense thermal cycling, which induces high residual ...

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
