Aiming at the current existing problems of study and fabrication of national aluminum sheet used for easy-open can without being pay more attention to the effects of intrinsic metallurgical defects, a new idea to link organically with hot deformation process in the study of the aluminum sheet used for easy-open can has been put forward by author.
针对目前我国铝材生产与研究中对内在冶金缺陷的影响作用重视不足、液态(熔体)处理与各种固态处理均是按各自系统独立进行研究的现状,作者结合本课题组的前期研究基础,以具有实用价值且量大面广的易拉罐用铝材(Al-Mn-Mg合金)作为研究对象,提出从改善铝材冶金质量这一关键技术入手,将铝材的处理状态(熔体处理和均匀化)与热变形加工有机地结合起来进行研究的新思路。
6) metallurgical defect
冶金缺陷
1.
