Prospects of Eliminating Fluorspar Consumption in a Sustainable Argon‐Oxygen‐Decarburization Process

steel research international, EarlyView.
This study aims at identifying pathways for eliminating fluorspar consumption in the argon‐oxygen‐decarburization (AOD) process. Thermodynamic calculations suggest the feasibility of completely replacing fluorspar with alternative fluxes such as Al2O3, Na2O, K2O, and Li2O of suitable amounts.

Numerical Investigation of Velocity and Thermal Slips on MHD Hybrid Nanofluid Flow Past a Stretching Sheet With nth‐Order Chemical Reaction Effects

Engineering Reports, Volume 8, Issue 4, April 2026.
The velocity and thermal slip boundary conditions on MHD hybrid nanofluid flow past a stretching sheet are examined. Hybrid nanofluids are used to enhance the heat transfer and thermal efficiency of the systems. The nth‐order chemical reaction effect is also taken into account.

A Future for Vacuum Arc Remelting and Electroslag Remelting—A Critical Perspective

Metals, 2023
In the secondary metals refining processes, vacuum arc remelting (VAR) and electroslag remelting (ESR), the consumable electrode is commonly produced by vacuum induction melting (VIM) which employs the regrettably primitive casting technique of simply pouring into the open top of the mold.

Coalescence‐Ripening Mechanism of γ′−Ni3(Al, Ti) During Long‐Term/High‐Temperature Operation of Ni‐Based Superalloy Discs

Rare Metals, Volume 45, Issue 3, March 2026.
ABSTRACT The evolution of the γ′−Ni3(Al, Ti) phase in superalloys is governed by a coupled coalescence‐ripening mechanism driven by elemental diffusion. In this study, thermal exposure experiments were performed at 750°C and 800°C for durations ranging from 100 to 20,000 h.

A Perspective on Powder Metallurgy and Additive Manufacturing of High‐Nitrogen Alloyed Stainless Steels

Advanced Engineering Materials, Volume 27, Issue 14, July 2025.
This perspective article explores an innovative powder metallurgical approach to producing high‐nitrogen steels by utilizing a mixture of stainless steel and Si3N4. This mixture undergoes hot isostatic pressing followed by direct quenching. The article also examines adapting this method to laser powder bed fusion (PBF‐LB/M) to overcome nitrogen ...
