Cohesive energies of Fe-based glass-forming alloys
M. Mihalkovič, M. Widom
We calculate the cohesive energies of Fe-based glass-forming alloys in the B-Fe-Y-Zr quaternary system. Our {\it ab-initio} calculations fully relax atomic positions and lattice pa…
Quasicrystal approximants with novel compositions and structures
M. Mihalkovic, M. Widom
We identify several new quasicrystal approximants in alloy systems in which quasicrystals have not been previously reported. Some occur in alloys with large size contrast between t…
Order-disorder transition in the Cd-Ca cubic approximant
M. Widom, M. Mihalkovic
Recent experiments discovered an order-disorder transition occuring at low temperatures in large unit 1/1 cell cubic approximants of the stable Cd-based binary alloy quasicrystals.…
Equilibrium structure of decagonal AlNiCo
S. Naidu, M. Mihalkovic, M. Widom
We investigate the high temperature decagonal quasicrystalline phase of AlNiCo using a quasilattice gas Monte-Carlo simulation. To avoid biasing towards a specifi…
Tile Hamiltonians for Decagonal Phases
M. Widom, I. Al-Lehyani, M. Mihalkovic
A tile Hamiltonian (TH) replaces the actual atomic interactions in a quasicrystal with effective interactions between and within tiles. We study Al-Co-Ni and Al-Co-Cu decagonal qua…
Tile Hamiltonian for Decagonal AlCoCu
Ibrahim Al-Lehyani, Mike Widom
A tile Hamiltonian (TH) replaces the actual atomic interactions in a quasicrystal with effective interactions between and within tiles. We studied Al-Co-Cu decagonal quasicrystals…
