文档介绍：I 航空铝合金冷压力学性能研究摘要铝合金作为飞机、航天器以及汽车轻量化的理想材料,已成为当前航空航天工业、汽车工业开发研究的热点,但其常温下难以加工成形,制约了铝合金的应用。因此对于铝合金,研究其冷压下的力学性能具有非凡的意义[1]。本文采用试验作为基本手段,研究固溶参数及变形量这两个对 7075 航空合金力学性能影响比较显著的因素。根据固溶热处理参数对合金显微组织的影响的研究确定一个较佳的固溶参数组合,先将试样按照较佳的固溶参数组合完成固溶热处理; 1每间隔 30min 完成一组(一组 5 个冷压缩量,分别 1%、2%、3%、4%、5%) 目标冷压缩量; 2在4个小时内完成 9组相同的工作; 3记录固溶热处理完成时间; 4记录每次冷压缩开始和结束时间; 5提供冷压缩原始数据; 6千分尺测试样尺寸变化,必要时可采用万能工具显微镜测试塑性变量和回弹量。关键词:铝合金,冷压,固溶参数,力学性能 II Effects of asymmetric rolling and heat treatment on mechanical properties of aluminium alloy Abstract In the present study, the orthogonal experiment method was used firstly for selecting the most significant factors affecting the mechanical properties of aluminiu m alloy from aging time and reduction of rolling 。 The following results have been obtained : (1) every 30min plete a group (a group of five pression, respectively, 1%, 2%, 3%, 4%, 5%) of pression of the target intervals; (2) Complete nine groups working within the same four hours (3) Record the data of the heat treatment time (4) Record each press start and end times (5)provide the original data of presses (6)Test sample size changes by micrometer , if necessary, can be used to test the plastic variable universal tool microscope and springback.
