Orientation relationship of quasicrystalline approximate phase η-Al5(Mn,Cr) in AA5083 aluminium alloy
ABSTRACT A quasicrystalline approximate monoclinic phase η-Al5(Mn,Cr) with a plate-like or rod-like morphology in AA5083 aluminium alloy was investigated using transmission electron microscopy. Several types of orientation relationships (ORs) between the η-Al5(Mn,Cr) phase and the α-Al matrix were observed and these ORs could be correlated with a rotation operation around the axis with an angle that is an integer times 18.5°. These multiple ORs were interpreted by utilizing an invariant deformation element model – a simplified version of three-dimensional invariant line strain analysis.
期刊介绍：
Philosophical Magazine Letters is the rapid communications part of the highly respected Philosophical Magazine, which was first published in 1798. Its Editors consider for publication short and timely contributions in the field of condensed matter describing original results, theories and concepts relating to the structure and properties of crystalline materials, ceramics, polymers, glasses, amorphous films, composites and soft matter. Articles emphasizing experimental, theoretical and modelling studies on solids, especially those that interpret behaviour on a microscopic, atomic or electronic scale, are particularly appropriate.
Manuscripts are considered on the strict condition that they have been submitted only to Philosophical Magazine Letters , that they have not been published already, and that they are not under consideration for publication elsewhere.
