英文摘要	Effects of Cu additions on microstructure and mechanical properties of Fe3Al-10%Ni bulk nanocrystalline prepared by aluminothermic reaction were studied. The microstructure was studied by OM, EPMA, XRD and TEM, and the hardness and compressive strength were measured. The results reveal that the low Cu content (2%) maintained the bcc crystal structure and resulted in a sharp decrease of the average grain size. However, high Cu contents (4% and 6%) caused the structure ordering to B2. The hardness increased after adding Cu. A high Cu content was not benefit to the plasticity. The yield strength increased slightly at 2% and 6% Cu, but decreased a lot at 4% Cu.
