摘　　要：通过调整2618A铝合金的合金化元素、挤压温度、挤压速度等参数,试验研究2618A铝合金棒材粗晶环深度控制方法,以获得最优工艺-数,保证棒材粗晶环深度达到最小范围,满足产品用户和标准规定的要求。经过对比试验与分析,最终得到通过控制Ti与Zr元素含量以及采用低温、慢速_压工艺达到控制粗晶环深度的方法。By adjusting alloying elements,extrusion temperature and extrusion speed of 2618A aluminum alloy,the coarse-grain-ring-depth control method of 2618A aluminum alloy bar was experimentally studied in order to obtain the optimal process parameters,to ensure the minimum range reached by the coarse grain ring depth,and to meet the requirements of product users and standards.Through comparative test and analysis,the method of controlling the depth of coarse grain ring is obtained by controlling the contents of Ti and Zr elements and adopting low temperature and extrusion speed.
