<p><P>PROBLEM TO BE SOLVED: To provide a joined body made of different kinds of metals of an iron based alloy member and an aluminum based alloy member by welding which can obtain advantages such as excellent joining strength and high productivity substantially similar to those by welding the same kind of members, and to provide a joining technique therefor. <P>SOLUTION: This joined body obtained by joining the iron based alloy member and the aluminum based alloy member by welding is characterized in that the joint part between the iron based alloy member and the aluminum based alloy member has a structure including a supersaturated solid solution phase in which aluminum enters into solid solution in iron in a supersaturated manner. <P>COPYRIGHT: (C)2006,JPO&NCIPI</p> |
