Abstract:
Techniques are described for the extraction onto carbon replicas of precipitates and inclusions from Mg and Al-based alloys for analytical transmission electron microscopy. EDX analysis of Mn precipitates from a Mg-Mn alloy illustrates the problems that can arise from spurious X-rays, caused by the use of a 3mm disc specimen.
