摘要	Microstructure and mechanical properties of bulk nanocrystalline Fe3Al based alloy with 5wt.% Cu prepared by aluminothermic reaction before and after annealed at 873, 1073 and 1273K for 8h were investigated. Microstructures of the alloy before and after the annealing consisted of a Fe-Al-Cu matrix, a little Al2O3 sphere and Fe3AlCx fiber phases. The matrix of the alloy before the annealing was composed a nanocrystalline phase with disordered bcc crystal structure and a little amorphous phase. The amorphous phase disappeared after the annealing and Fe3Al phase with ordered DO3 structure appeared in the alloy after annealed at 1073 and 1273K in the matrix of the alloy. Size of the Fe3AlCx fiber phase increased with the annealing temperature. The alloy after the annealing had better plasticity, higher yield strength than that of the alloy before the annealing, and the alloy after annealed at 1273K had the highest yield strength. © 2011 Elsevier B.V.
