Analysis of Slag Conditioners for Foam Control by Coupling Thermodynamic Calculations and Machine Learning Models

International Journal of Ceramic Engineering &Science, Volume 8, Issue 3, May 2026.
This work combined computational thermodynamics and ML models to predict slag properties and, consequently, the foam aging times. Using this framework, three alternative slag conditioners were investigated to control slag foaming in the EAF. ABSTRACT The slag foaming practice enables high energy efficiency in the electric arc furnace, and its ...

First-Principles Calculation of the Cu-Li Phase Diagram [PDF]

, 2004
We present first-principles calculations of the solid-state portion of the Cu-Li phase diagram based on the cluster expansion formalism coupled with the use of (i) bond length-dependent transferable force constants and lattice dynamics calculations to ...

First-principles modeling of temperature and concentration dependent solubility in the phase separating Fe$_x$Cu$_{1-x}$ alloy system

, 2012
We present a novel cluster-expansion (CE) approach for the first-principles modeling of temperature and concentration dependent alloy properties. While the standard CE method includes temperature effects only via the configurational entropy in Monte ...

Discovery of high-entropy ceramics via machine learning [PDF]

, 2020
Although high-entropy materials are attracting considerable interest due to a combination of useful properties and promising applications, predicting their formation remains a hindrance for rational discovery of new systems.

Complexion‐Mediated Dislocation Transfer Enables Exceptional Strength‐Toughness Synergy in Multicomponent‐Alloy Bonded Hardmetal

Rare Metals, Volume 45, Issue 5, May 2026.
ABSTRACT The inherent brittleness of hardmetals stems from the rigid covalent bond in the ceramic matrix and the sharp ceramic/metal interface, which restricts the nucleation and motion of dislocations. In this study, a novel strategy is proposed to activate significant dislocation behaviors in the WC matrix by employing a non‐equiatomic CoNiFeCr ...

Egyensúlyi fázisdiagrammok számítása ESTPHAD módszerrel = Calculation of Equilibrium Phase Diagrams by ESTPHAD method [PDF]

, 2008
Az egyensúlyi fázisdiagramok igen jelentős része csak grafikusan ismert, vagy - egy csekély hányaduk -komplikált, igen hosszú CPU időt lekötő eljárással számítható ki. Ez a felismerés vezetett az ESTPHAD módszer és szoftver kidolgozásához.

Influence of Laser Powder‐Based Directed Energy Deposition and Heat Treatment on the Thermal Conductivity of Cold‐Work Tool Steel X65MoCrWV3‐2

steel research international, Volume 97, Issue 5, Page 2796-2804, May 2026.
The studied X65MoCrWV3‐2 press hardening tool steel, produced via laser‐based direct energy deposition DED‐LB/M, exhibits a 15‐20% lower thermal conductivity than its conventionally produced equivalent when heat‐treated to operational hardness. The microstructural evolution during the employed direct tempering leads to anisotropic thermal transport, as

Liquidus of MgO and MgAl2O4 in the CaO‐MgO‐Al2O3 System at 1550 and 1600°C

Journal of the American Ceramic Society, Volume 109, Issue 5, May 2026.
ABSTRACT In this study, the liquidus of MgO and MgAl2O4 spinel phase in the CaO‐MgO‐Al2O3 system at 1550 and 1600°C were experimentally investigated using a classical quenching method. In order to examine the liquidus composition accurately, the equilibration was carried out using four different ways using the combinations of Pt and ceramic (MgO and ...

About the Reliability of CALPHAD Predictions in Multicomponent Systems

Entropy, 2018
This study examines one of the limitations of CALPHAD databases when applied to high entropy alloys and complex concentrated alloys. We estimate the level of the thermodynamic description, which is still sufficient to correctly predict thermodynamic ...
