Simulation of alnico coercivity

Coercivity Enhancement and Gamma Phase Avoidance of Alnico Alloys

The promotion of social progress requires greater levels of energy efficiency, quality and productivity. However, these developments usually come at the cost of the environment. Green technologies such as electric vehicles, wind turbine and solar panels are ironically overshadowed by supply limitations and high prices of rare earth elements. Therefore, it is important to find alternative materi...

Equilibrium structure of decagonal AlNiCo

We investigate the high temperature decagonal quasicrystalline phase of Al72Ni20Co8 using a quasilattice gas Monte-Carlo simulation. To avoid biasing towards a specific model we use an over-dense site list with a large fraction of free sites, permitting the simulation to explore an extended region of perpendicular space. Representing the atomic surface occupancy in a basis of harmonic functions...

Atomic surface occupancy of decagonal AlNiCo

We investigate the atomic surface structure of the high temperature decagonal quasicrystalline phase of Al72Ni20Co8 using a lattice gas Monte-Carlo simulation. To avoid biasing towards a specific model we use an over-dense site list with a large fraction of free sites, permitting the simulation to explore an extended region of perpendicular space.

Combined energy – diffraction data refinement of decagonal AlNiCo

We incorporate realistic pair potential energies directly into a non-linear least-square fit of diffraction data to quantitatively compare structure models with experiment for the Ni-rich d(AlNiCo) quasicrystal. The initial structure models are derived from a few a priori assumptions (gross features of the Patterson function) and the pair potentials. In place of the common hyperspace approach t...
