This work investigates the microstructure-property linkages in magnesium (Mg) with an emphasis on understanding interaction effects between grain size, texture, and loading orientation. A single crystal plasticity framework endowed experimentally informed micro Hall-Petch type relations for activation thresholds slip twinning is adopted to resolve polycrystalline microstructures over a broad te...

A new approach to modelling the microstructure evolution and yield strength in laser powder bed fusion components is introduced. Restoration mechanisms such as discontinuous dynamic recrystallization, continuous recovery were found be activated during of austenitic stainless steels; these are modelled both via classical Zener-Hollomon thermostatistical approaches. mechanism suggested for format...

The shear failure mechanism of polycrystalline gas hydrates is critical for understanding marine geohazards related to under a changing climate and safe recovery from hydrate reservoirs. Since current experimental techniques cannot resolve the on spatial temporal nanoscale, molecular simulations can assist with proposing substantiating nanoscale mechanisms. Here, we report methane using direct ...

[1] We examine numerically the influence of Hall effect corrections to Ohm’s law upon the decay of homogeneous compressible magnetohydrodynamic turbulence and conclude that there are no significant differences in global decay rate associated with the Hall effect. This affirms expectations that energy decay is controlled by the large-scale eddies.

We develop a systematic theory of the Hall effect in Q1D conductors in both weak and strong magnetic fields for a model where the electron relaxation time varies over the Fermi surface. At high temperatures, the Hall coefficient saturates at the values −β/ecn, where the dimensionless coefficient β is determined by the curvature of the longitudinal dispersion law of electrons, e the electron cha...

It is known that exact magnetic reconnection solutions can be constructed for collisionally dominated resistive plasmas. In this paper we refine the collisional resistive description by invoking an Ohm’s law that includes Hall current and plasma inertial contributions. We first demonstrate the surprising fact that the analytic treatment of both two and three dimensional current sheet reconnecti...
