【求助】变速箱壳体和车身面板铸造时，分别对的Mg-Al合金要求和铸造方法？
|
|
relatively good fluidity and castability, when the Al content is in the range 6-9wt%, and relatively good ductility when the Al content is below 4 wt%. For a Mg-Al alloy transmission housing and a Mg-Al alloy sheet for fabricating car body panel. which composition and which casting technologies (among sand casting, high-pressure die casting, and twin-roll casting technologies) would you select for fabricating them? What is the basis of your selection? How to achieve the useful mechanical properties in these two components? 镁铝合金相图会对分析有帮助。 大家帮忙答一答~谢谢 ding2008212整理 [ Last edited by ding2008212 on 2011-4-21 at 14:11 ] |
