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 Al12...
