A CALculation of PHAse Diagrams thermodynamic modeling for Fe–Sn–C system is carried out. The model and the developed database can be used to calculate phase diagrams and thermodynamic properties of this system over wide temperature/composition range, and a part of a larger thermodynamic database for steel and alloy system, and effectively used to ...

Recycling of Mill Scale Into High‐Purity Iron Through Hydrogen‐Based Reduction
Mill scale, an iron oxide–rich steel by‐product, is difficult to recycle due to impurities. This study evaluates hydrogen‐based direct reduction and hydrogen plasma smelting reduction as low‐carbon recycling routes. Impurity segregation limits reduction kinetics. Direct reduction achieves 92% conversion in 180 min, while plasma reduction reaches 91% in

This study uses in situ synchrotron X‐ray diffraction at the German Electron Synchrotron to analyze low‐pressure carburizing (LPC) in steels. The findings reveal surface carbon saturation and carbide formation kinetics, and phase‐specific stress development during quenching. The results show carbide kinetics depend on steel grade and size, while stress

Soda Ash Free Batches for Novel Container Glass Compositions
A series of novel glass compositions incorporating up to 50% recycled cullet is melted from batches free of soda ash. Their viscosity–temperature, liquidus, and electrical conductivity characteristics are comparable to conventional soda–lime—silica glasses, enabling processing in conventional installations while markedly reducing batch‐to‐melt ...

A numerical model resulting from irreversible thermodynamics for describing transport processes is introduced, focusing on thermodynamic activity gradients as the actual driving force for diffusion. Implemented in CUDA C++ and using CalPhaD methods for determining the necessary activity data, the model accurately simulates interdiffusion in aluminum ...

Phase‐Field Simulation for the Microstructural Evolution of CuPb2F6 During Defluorination
A CALPHAD‐coupled phase‐field model uncovers how discharge rate and nucleation density control Cu nanoparticle formation in CuPb2F6 cathodes. Faster kinetics produce finer particles governed by concentration gradients, enhancing reversible capacity.
