摘要	Extruded 15 vol.% SiCp/Al-Cu-Mg composite was friction-stir-welded (FSW) and subjected to subsequent post-weld T4-treatment. The formation of Cu2FeAl7 phase with Fe resulting from steel tool wear was identified at or near the SiC particle interfaces by using transmission electron microscopy, high-resolution electron microscopy and differential scanning calorimetry. Two types of Cu2FeAl7 phases were observed: a single crystal phase and a polycrystalline nanostructured phase. No elemental iron was detected. The formation mechanism of the Cu2FeAl7 phase is discussed. (C) 2007 Acta Materialia Inc. Published by Elsevier Ltd. All rights reserved.
