Extraction of second phases from magnesium and aluminum alloys for analytical electron microscopy

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...

Zusammenfassung:	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. Published 1994 Wiley‐Liss, Inc.
