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

open access: yessteel 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

The Application of Hydrochar Composite Briquettes for Sustainable Slag Foaming in the Electric Arc Furnace Process

open access: yessteel research international, EarlyView.
Hydrochar‐mill‐scale briquettes with varying C/O molar ratios (0.07–0.90) have been tested at 1650 °C to evaluate their slag foaming performance for electric arc furnace application. All seven briquette recipes developed succeed in promoting slag foaming.

Cement Lines are Stiffer and Harder than Bone but Exhibit Different Mineral–Mechanics Relationships due to Thicker and Shorter Mineral Particles

open access: yesSmall Structures, EarlyView.
Bone's complex hierarchical structure contains many internal interfaces, including the cement line (CL) around osteons. This article shows that the CL is stiffer and harder than surrounding bone but has different mineral–mechanics relationships. These findings challenge the view of the CL as a soft, protective interface and provide insights for ...
