Decoding α‐MoC1−x Nanoparticle Formation in Continuous Flow via Machine Learning

Small, EarlyView.
Formation pathway of α‐MoC1−x nanoparticles synthesized from oleylamine‐Mo(CO)6 precursor under mild continuous‐flow conditions was investigated. By combining in‐line spectroscopic monitoring with a machine learning (ML) framework capable of deconvoluting complex, overlapping spectral features, we reveal mechanistic details of early‐transition‐metal ...

In Situ Investigation of Microstructure Evolution and Stress Generation During Low‐Pressure Carburizing and Quenching by Means of Synchrotron X‐Ray Diffraction

steel research international, EarlyView.
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
