This review paper focuses on dislocations and plastic deformation in magnesium oxide
crystals. MgO is an archetype ionic ceramic with refractory properties which is of interest in …

In the Earth's middle and lower crust and mantle, rocks deform by creep, and it has long
been recognized that lattice preferred orientations (LPO) of the mineral constituents in …

6061 O Al alloy foils were welded to form monolithic and SiC fibre-embedded samples using
the ultrasonic consolidation (UC) process. Contact pressures of 135, 155 and 175MPa were …

We present an electron backscatter diffraction, cathodoluminescence, and radiogenic U-Pb
dating study of large zircon grains (0.8–1.5 mm) that show evidence of intracrystalline …

In order to shed light on the cause for onset of strain localisation in plagioclase-rich rocks we
have performed detailed microstructural analyses on a sheared anorthosite–leucogabbro …

Summary The Weighted Burgers Vector (WBV) is defined here as the sum, over all types of
dislocations, of [(density of intersections of dislocation lines with a map)×(Burgers vector)] …

Bulk, polycrystalline (Co, Cu, Mg, Ni, Zn) O was synthesized using solid-state sintering.
Micropillars were prepared and mechanically deformed along three crystallographic …

Shearing of magma during ascent can promote strain localisation near the conduit margins.
Any mechanical and thermal discontinuities associated with such events may alter the …

A hierarchical multi-scale model was used to study the effect of high pressure on the critical
shear stresses of MgO. The two main slip systems, ½⟨ 110⟩{110} and ½⟨ 110⟩{100}, were …

Determination of the controlling nucleation and recrystallisation mechanisms from a samples
microstructure are essential for understanding how the microstructure formed and evolved …
