英文摘要	The effects of annealing on microstructure and mechanical properties of bulk nanocrystalline Fe3Al based alloy with 10 wt. % Ni prepared by aluminothermic reaction have been investigated. It was found that crystal structure of the alloy did not change after annealing at 600 and 800 degrees C, while it changed to ordered B-2 and nanocrystalline grains orientations became random after annealing at 1000 degrees C. Average grain sizes of the alloy changed a little after annealing at different temperatures. The alloy after annealing had a large plastic deformation in compression at room temperature and the alloy annealed at 800 degrees C had the highest compressive yield strength of 1351 MPa. The alloy without annealing had much lower flow stress and good creep property in compression at 800 and 1000 degrees C.
