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.

Barriers to Steel Decarbonization

steel research international, EarlyView.
Main identified barriers to steel decarbonization Carbon dioxide (CO2) emissions are a leading contributor to global climate change, necessitating urgent mitigation strategies. While various metrics—such as total national emissions, per‐capita output, and historical contributions—define responsibility, determining accountability remains complex ...

Analyses of the Deformability and Chemistry of Non‐Metallic Inclusions in QT Steels With Increased Recycling‐Induced Tramp Element Content

steel research international, EarlyView.
This work uses high‐temperature dilatometry to examine how the tramp elements Cu, Ni, and Sn affect the deformability of non‐metallic inclusions and matrix in quench‐and‐temper steel. Mg‐bearing inclusions deform less than Mg‐free ones. Copper lowers formability. Nickel increases deformability.

Phase evolution behaviour of dolomite-alumina system [PDF]

, 2014
Magnesium Aluminate Spinel Refractories are usually prepared by sintering from Calcium Aluminate Cement and Synthetic Mag-Al spinel. But the high cost of electrofused or sintered spinels is a hindrance and hence a suitable alternative is required ...

Monitoring of historical structural materials with computed tomography

Structural Concrete, EarlyView.
Abstract Computed tomography (CT) is an excellent tool to solve certain engineering problems connected to material science (such as sulfate swelling, internal degradation due to freezing, and alkali silicate swelling) and to understand specific processes (frost peeling, acid action).

Mothers against the natural order: Gender representations and desertion of identities in the drama of disinheriting a son in eighteenth‐century Barcelona  

Gender &History, EarlyView.
ABSTRACT The disinheritance of a firstborn son accustomed to the privileges of exclusion has for centuries been a dramatic event for families, especially if the decision was taken by a woman, the son's own mother. Very few dared to do so, because it symbolised a break with the notion of virtuous, compassionate motherhood; it represented a failure to be
