Natural Aging of AlMg5Si2Mn Casting Alloy

The as-cast and heat treated structure of permanent mould and high pressure die castings of the AlMg5Si2Mn alloy has been investigated by differential scanning calorimetry, microhardness measurements, transmission electron microscopy and energy dispersive X-ray analysis. Curved plate-like precipitates were detected for both alloys inside the -Al grains.
