摘要：
After 80 h of milling the elemental powders, mechanical alloying of Al90Fe5Nd5 produces a nanostructured composite, which consists of nanocrystals of fcc-Al and some Al11Nd3 precipitates, embedded in an amorphous matrix. This composite ha's a Vickers hardness of 2.8 GPa and is thermally stable up to about 340 degrees C. Above this temperature it decomposes into Al11Nd3 and Al10Fe2Nd phases.
