Al-Mg合金预变形以及热处理对表面斜纹的影响王能均西南铝业(集团)有限责任公司摘 要:针对Al-Mg合金板材在变形过程中出现的表面斜纹,对比了Al-Mg合金与其他硬合金的应力-应变曲线特征差异,分析了表面纹路的形成机理以及形貌与应力-应变曲线的对应关系.根据不同应力-应变曲线形貌,开展了0%~5%不同预变形工艺,490~550℃范围加热,炉冷,水冷以及保温时间等退火工艺对材料性能和组织的影响研究.结果表明:退火后增加到2%以上的预变形可以有效解决屈服平台,但对锯齿状形貌没有改善.采用在510~540℃加热+水冷方式退火可以有效解决屈服平台和锯齿状形貌,并最终通过工业化验证,有效解决了表面斜纹问题.关键词:Al-Mg合金;斜纹;预变形;退火;......
