Abstract: By nickel electroplating at room temperature, the specimen preparation of ultra-sonic gas atomized aluminum alloy powders for observation in transmission electron microscope was carried out. The advantages of this technique are simple technologically and convenient practically. The nickel and the powders combine well in the plated sheet which can be thinned by ion milling. The powders in the thinned sheet possess large thinned area and can be examined in common TEM for the studies of their microstructure.
Key words: aluminum alloys; powders; electroplating; transmission electron microscope
