Large grain-size-dependent rheology contrasts of halite at low differential stress: evidence from microstructural study of naturally deformed gneissic Zechstein 2 rock salt (Kristallbrockensalz) from the northern Netherlands [PDF]
Constitutive laws to predict long-term deformation of solution-mined caverns and radioactive-waste repositories in rock salt play an important role in the energy transition. Much of this deformation is at differential stresses of a few megapascals, while

Study on estimation method of methane permeability in coal
The gas flow path in coal body is mainly composed of slits and pores, which is a typical dual gas flow path structure. Generally, in order to quantify the apparent permeability of gas transport in different scale flow paths, mathematical models of ...

Electron microscopy of Cu − SiC composites: a cold-molding and solid phase sintering [PDF]
Cu − SiC composites were studied by scanning electron microscopy after processes of molding and a heat treatment. After pressing, plastic deformation of copper particles and traces of destruction of silicon carbide (cracks and debris) are observed. After
