Evaluating Plasma Torches as a Low‐Decarburization Preheating Method for MgO–C Refractory Linings

steel research international, EarlyView.
This study evaluates direct current (DC) plasma torches using nitrogen as an alternative preheating method for magnesia‐carbon (MgO–C) refractory‐lined ladles. Full‐scale trials at 0.7 and 1.5 MW are compared to conventional gas burner. Plasma‐heated samples show lower decarburization and improved surface integrity due to partial sintering and reduced ...

Numerical Prediction of Deformation‐Induced Martensitic Transformation in Cold‐Sprayed Austenitic Stainless Steel

steel research international, EarlyView.
Cold spray deposition of stainless steel (grade: SS304) is evaluated for marine applications, with emphasis on martensitic transformation during impact. Analytical modeling, simulations, and experiments reveal that helium‐assisted spraying of fine powders promotes cooling below the martensitic start temperature, enabling up to ≈40% austenite to ...

A Thermodynamic‐Kinetic Model for Basic Oxygen Furnace Tapping: Improved Prediction of Phosphorus and Steel‐Slag Evolution

steel research international, EarlyView.
This study develops a thermodynamic–kinetic model for basic oxygen furnace tapping and validates its accuracy under near‐equilibrium and far‐from‐equilibrium initial conditions. Comparison with a reference model demonstrates its broader applicability. The model further reveals the evolution of key steel and slag components, providing new transparency ...

Microstructure Evolution in Directionally Solidified Fe–C–Mn–(Si) Peritectic Steels

steel research international, EarlyView.
This study investigates how growth velocity and silicon additions affect dendritic morphology, primary arm spacing, and mushy‐zone evolution in directionally solidified quaternary peritectic steels. Silicon substantially broadens the freezing range and lengthens the mushy zone, increasing susceptibility to interdendritic cracking.

Compression capacity of closely spaced double‐angle beam‐columns – Impact of joint stiffness

Steel Construction, EarlyView.
Abstract Usually, pinned ends are assumed to calculate the compression capacity of closely spaced double‐angle members. In reality, the joints used in practice provide additional rotational restraint at the member's ends, which significantly influence the compression member capacity of such built‐up sections.
