Abstract
The grain boundary crystallographic misorientations of magnetic pulse welded (MPW) AA6061-T6 in linear and tubular configurations were examined using the electron backscattered diffraction (EBSD) technique. A refined structure of heavily deformed grains with higher grain boundary angles was observed in linear welds. Significant spalling was observed away from the welded region, in the interior of tubular welds. The results show the complex interaction of shock waves with the materials during this impact welding process.
