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.

MetalMat, Volume 3, Issue 1, March 2026.This review highlights recent advancements in Severe Plastic Deformation (SPD) techniques tailored for tubular samples. The mechanisms of processing are critically discussed with emphasis on microstructural control and the governing process parameters that enable refinement to ultrafine‐ and nano‐grained structures. Comparative insights into equivalent

Forming of bulk metallic glasses: ideal superplasticity?
, 2012 International audienceDue to their brittleness, bulk metallic glasses (BMG) are generally difficult to form at room temperature. A fruitful way to get components is to deform them in their supercooled liquid region (SLR).

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 ...
