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? þÂÁºÏ½ðÏàͼ»á¶Ô·ÖÎöÓаïÖú¡£ ´ó¼Ò°ïæ´ðÒ»´ð~лл ding2008212ÕûÀí [ Last edited by ding2008212 on 2011-4-21 at 14:11 ] |
