Abstract

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.

AA5083铝合金准晶近似相η-Al5（Mn，Cr）的取向关系

摘要:用透射电镜研究了AA5083铝合金中近似单斜晶的片状或棒状η-Al5(Mn,Cr)相。观察到η-Al5(Mn,Cr)相与α-Al基体之间存在几种类型的取向关系(ORs)，这些取向关系可能与绕轴旋转18.5°的整数倍的角度有关。使用不变变形单元模型-三维不变线应变分析的简化版本来解释这些多个ORs。

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.
