Characteristics of Carbon Monoxide and Ethylene Generation in Mine’s Closed Fire Zone and Their Influence on Methane Explosion Limits

Fire
Methane explosions often occur during the closure process of mine fire zones, during which the concentration of combustible gases such as monoxide and ethylene produced by coal combustion dynamically changes, which changes the risk of methane explosion ...

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, Volume 97, Issue 7, Page 3642-3662, July 2026.
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
