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 ...

A theoretical review of the operation of vibratory stress relief with particular reference to the stabilization of large-scale fabrications [PDF]
, 2011 Vibratory stress relief (VSR) is widely used on large welded fabrications to stabilize the structures so that they do not distort during further machining or during operational duty.

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.

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 ...

Evolution of Austenite Microstructure and Precipitation State during Hot Rolling of a Nb-Microalloyed Steel [PDF]
, 2003 Hot torsion tests were used to simulate hot rolling of a Nb-microalloyed steel. Subsequent graphic representation of Mean Flow Stress (MFS) versus the inverse of absolute temperature for each pass allowed to know the critical rolling temperatures (Tnr ...
