摘要：

In order to increase the modifying effect, the Fe-V-Nb alloy was rapidly solidified with melt-spin method, and the nano-sized ribbon was gained at 40-45 rad/s. Subsequently, Fe-Si-Mn spring steels was modified by amorphous and nanocrystalline. The results show that the microscopic stnicture of Fe-Si-Mn spring steels modified by amorphous and nanocrystalline is better than micro-alloyed with the same amount of niobium and vanadium, the mechanical properties of Fe-Si-Mn spring steels modified by Fe-V-Nb intermediate alloy are improved evidently: the yield-strength is reached to 1484 Mpa, the yield ratio is reached to 0.94 and the hardness is reached to 64HRC when specimens quenched.
