摘要：

Defects causing stress concentration from electron beam welding are related to the Al content of the Mg-AI-Zn weldment and its effect will be most conspicuous for the welding of dissimilar metals. Precipitates which are gamma phase (Mg-17(Al,Zn)(12)) also influence the formative mechanism of pores, the heat-affected zone and the fracture mode of the weld. More noteworthy is that the Al content of 6.0 wt.% is a very important delimitation for these mechanisms. (c) 2007 Acta Materialia Inc. Published by Elsevier Ltd. All rights reserved.
