Insoluble intermetallic particles have been extracted from the complex Al (Mg, Si, Cu, Mn, Cr, Fe) alloy (designated 6010) using an extraction solution containing 8-hydroxyquinoline. The extracted particles were analysed using both X-ray diffraction and energy dispersive analysis techniques in the transmission electron microscope. The particles were found to be the cubic α-Al(Fe Mn)Si phase. Analysis showed two distinct compositions for the phase: larger particles (>0.5 μm) had a much higher iron content and lower silicon content than smaller particles. The absorption of other solute elements into these particles during an ageing treatment was noted. © 1981 Chapman and Hall Ltd.
