Abstract

ABSTRACT The occurrence of grain boundary precipitates was investigated with respect to the crystallographic orientation of the adjacent grains in extruded AA6110, AA6063 and AA6061 alloys brought to T6 temper. It was found that the requirement for grain boundary precipitate formation is for the adjacent grains to have <100>Al directions or {100}Al planes parallel to the grain boundary plane. The highest density of grain boundary precipitates was present when this requirement was fulfilled by both adjacent grains.

Al-Mg-Si(-Cu)合金中晶界析出相形成与相邻晶粒取向的关系

摘要研究了挤压AA6110、AA6063和AA6061合金在T6回火条件下，晶界析出相的发生与相邻晶粒的结晶取向有关。发现晶界沉淀物形成的要求是相邻晶粒具有Al方向或{100}Al平行于晶界平面的平面。当两个相邻晶粒都满足这一要求时，晶界沉淀物的密度最高。

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.
