Icosahedral Alloys : Phase Purity and Phason Strains
نویسندگان
چکیده
We present a survey of x-ray and electron diffraction studies of Aluminumn Metal alloys. The icosahedral phase is found in A1 alloyed with Mn, Cr, V, Mo, Ru, W, and Re. The effect of adding small amounts of Si and Ru to the binary alloys is discussed. We review the advantages and disadvantages of various indexing schemes. Distortions of electron diffraction pictures are described in terms of phason strains in a quasilattice.

Phonon-Phason coupling in icosahedral quasicrystals
– From relaxation simulations of decoration-based quasicrystal structure models using microscopically based interatomic pair potentials, we have calculated the (usually neglected) phonon-phason coupling constant. Its sign is opposite for the two alloys studied, i-AlMn and i-(Al,Cu)Li; a dimensionless measure of its magnitude relative to the phonon and phason elastic constants is of order 1/10, ...
متن کاملNon-linear generalized elasticity of icosahedral quasicrystals
Quasicrystals can carry, in addition to the classical phonon displacement field, a phason displacement field, which requires a generalized theory of elasticity. In this paper, the third-order strain invariants (including phason strain) of icosahedral quasicrystals are determined. They are connected with 20 independent third-order elastic constants. By means of non-linear elasticity, phason stra...
متن کاملMetadislocations in Complex Metallic Alloys
Complex Metallic Alloys (CMAs) represent a large group of crystalline intermetallics comprising some hundreds of known phases in various alloy systems. They are characterized by the presence of icosahedral atom coordination, large lattice constants, and a correspondingly large number of atoms per unit cell, typically ranging between a few tens and some thousand [1]. In recent years, CMAs have a...
متن کاملIcosahedral quasicrystals with continuous phasons
2014 A variety of models for icosahedral quasicrystals is constructed such that atoms move continuously under displacements along the phason space R3*, while their positions are separated by distances larger than some h > 0, a « hard core » diameter. The models exhibit icosahedral symmetry and the diffraction properties of perfect quasiperiodic structures. J. Phys. France 50 (1989) 3181-31...
متن کاملMechanisms of plastic deformation of icosahedral quasicrystals
Icosahedral quasicrystals deform plastically by dislocation motion. The deformation behaviour can be modelled by simple equations of dislocation mobility, the damage of the quasicrystal structure and the kinetics of dislocation evolution, but fundamental questions are still discussed, like the mode of dislocation motion (glide or climb) and the role of phason defects. 2003 Acta Materialia Inc. ...
