本文针对7A04预拉伸厚板出现的暗灰色条纹,从宏观组织、显微组织、机械性能、阳极氧化、热处理等多方面进行了观察与试验. 证明7A04 45mm预拉伸厚板暗灰色条纹的实质是由于该处的化合物数量多于其它部位;暗灰色条纹的存在对7A04 45mm预拉伸厚板的机械性能没有影响,但是它影响板材加工件的外观质量. 同时对暗灰色条纹的产生原因进行了讨论.
本文針對7A04預拉伸厚闆齣現的暗灰色條紋,從宏觀組織、顯微組織、機械性能、暘極氧化、熱處理等多方麵進行瞭觀察與試驗. 證明7A04 45mm預拉伸厚闆暗灰色條紋的實質是由于該處的化閤物數量多于其它部位;暗灰色條紋的存在對7A04 45mm預拉伸厚闆的機械性能沒有影響,但是它影響闆材加工件的外觀質量. 同時對暗灰色條紋的產生原因進行瞭討論.

In the this article observation and test have been done for thick dark grey stripe found in 7A04 aluminum alloy pre-stretched, in the aspects of macrostructure, microstructure, mechanical properties, anodic oxidation, heat treatment and etc., that proves thick dark gray stripe in 7A04 45mm pre-stretched is that the compound quantity is higher than other parts, and dark gray stripe does not affect on the mechanical properties of 7A04 45mm pre-stretched thick plate, but it affects the appearance quality of plate processing.At the same time, the reasons of the dark gray stripe are discussed.
