Crystallization process of amorphous Fe_<80>P_<12>C_6Mo_<0.5>Si_<1.5> alloy is observed at 733K by in-situ TEM. Results show that crystalline process of this alloy presents three-step type, i.e. incubation, phase separation and crystallization. Before precipitation of bcc-Fe, [200] and [220] diffraction rings of cubic-carbon appear first. With the increase of annealing time, these diffraction rings of cubic-carbon disappear. The bcc-Fe grains of Fe_<80>P_<12>C_6Mo_<0.5>Si_<1.5> and Fe_<79.5>P_<12>C_6Cu_<0.5>Si_<1.5> alloy, annealed at 673K, present different morphology. Copper is necessary in the formation of FePC based nanocrystalline alloy.
