Self-Assembly of Monatomic Complex Crystals and Quasicrystals with a Double-Well Interaction Potential
Michael Engel, Hans-Rainer Trebin
For the study of crystal formation and dynamics we introduce a simple two-dimensional monatomic model system with a parametrized interaction potential. We find in molecular dynamic…
Structure factors of harmonic and anharmonic Fibonacci chains by molecular dynamics simulations
Michael Engel, Steffen Sonntag, Hansjörg Lipp +1
The dynamics of quasicrystals is characterized by the existence of phason excitations in addition to the usual phonon modes. In order to investigate their interplay on an elementar…
Fracture of complex metallic alloys: An atomistic study of model systems
F. Rösch, H. -R. Trebin, P. Gumbsch
Molecular dynamics simulations of crack propagation are performed for two extreme cases of complex metallic alloys (CMAs): In a model quasicrystal the structure is determined by cl…
Tiling models for metadislocations in AlPdMn approximants
Michael Engel, Hans-Rainer Trebin
The AlPdMn quasicrystal approximants xi, xi', and xi'_n of the 1.6 nm decagonal phase and R, T, and T_n of the 1.2 nm decagonal phase can be viewed as arrangements of cluster colum…
A unified projection formalism for the Al-Pd-Mn quasicrystal Xi-approximants and their metadislocations
Michael Engel, Hans-Rainer Trebin
The approximants xi, xi' and xi'_n of the quasicrystal Al-Mn-Pd display most interesting plastic properties as for example phason-induced deformation processes (Klein, H., Audier,…
Dynamic fracture of icosahedral model quasicrystals: A molecular dynamics study
F. Rösch, Ch. Rudhart, J. Roth +2
Ebert et al. [Phys. Rev. Lett. 77, 3827 (1996)] have fractured icosahedral Al-Mn-Pd single crystals in ultrahigh vacuum and have investigated the cleavage planes in-situ by scannin…
