Abstract

In the present work, accumulative roll bonding (ARB) was used as an effective method for the process of nano/ultrafine-grained AA6063 alloy. Microstructural characteristics indicate considerable grain refinement leading to an average grain size of less than 200 nm after 7 ARB cycles. Texture analysis showed that 1-cycle ARB formed a strong texture near the copper component ({112}<111>). However, texture transition appeared by increasing the number of ARB cycles and after the 7-cycle of ARB, the texture was mainly developed close to the rotated cube component ({100}<110>). The results originated from mechanical properties indicated a substantial increment in strength and microhardness besides a meaningful drop of ductility after the 7 ARB cycles.

堆积滚焊工艺制备纳米/超细晶粒AA6063合金的组织与力学性能

本文采用累积滚轧法（ARB）对纳米/超细晶粒AA6063合金进行了工艺研究。微观结构特征表明相当大的晶粒细化，导致在7次ARB循环后平均晶粒尺寸小于200nm。织构分析表明，1周期ARB在铜组分附近形成了强烈的织构（{112}）。然而，纹理转变是通过增加ARB循环次数而出现的，并且在ARB的7个循环之后，纹理主要在旋转立方体分量附近发展（{100}）。来自机械性能的结果表明，在7次ARB循环后，强度和显微硬度显著增加，延展性显著下降。

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
