| Abstract: |
Basic research has been done on diffusion-welded joints with the overall aim of an adjustedinterface design. The phase formation of aluminium alloy / magnesium alloy bonds has been revealedby X-ray diffraction, energy-dispersive spectroscopy and electron back-scatter diffraction. Thepresence of Al12Mg17 and Al3Mg2 precipitates has been confirmed where the microstructure of theinterface comprises Al3Mg2 and Al12Mg17 as a bi-layer. The distribution and microstructure of theformed intermetallics and the arrangement of the precipitates originating from the alloys have beendetermined. Precipitates originating from the alloys agglomerate in the bi-layered welding zone. Theirarrangement in combination with the grain boundary evolution of the intermetallics and the change ofthe aluminium base solid solution in the interface region has a significant influence on the mechanicalproperties of the joint. |
