Frequency Dependence of Cationic Interdiffusion Kinetics in Er2O3/Y2O3 Diffusion Couples Under AC Flash Events

Journal of the American Ceramic Society, Volume 109, Issue 4, April 2026.
ABSTRACT The cationic interdiffusion behavior during flash events was investigated using Er2O3/Y2O3 diffusion couples under alternating current (AC) electric fields at different frequencies (50–2000 Hz) with similar specimen temperatures. The diffusion length of Er3+ in the Y2O3 body was athermally enhanced with increasing frequency.

Mechanochemical Enhancement of Siderite‐To‐Magnetite Conversion in Faults

Geophysical Research Letters, Volume 53, Issue 5, 16 March 2026.
Abstract Magnetic phases in fault rocks offer potential “geothermometers” for estimating frictional heating during fault slip. However, the thermochemical kinetics of magnetic minerals subjected to shear deformation in hydrothermal fluids‐conditions typical of natural faults ‐ remains poorly understood, hindering accurate temperature estimates.

Fracture‐Assisted Pressure Solution Creep of Granite: An Example From the Mont Blanc Massif, Western Alps

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 2, February 2026.
Abstract The Mont Blanc granite, as other deformed granites, has splitting properties attributed to two perpendicular planes: one formed by aligned fractures and the other by aligned micas in foliation planes. It is shown that this microstructure results from ductile deformation with stress‐driven dissolution of quartz and feldspar that passively ...
