摘要

Both Nb and Mo additions play a vital role in FeCo-based alloys and it is crucial to understand their roles and contents on thermal behavior,microstructural feature and magnetic property of alloys.Nanocrystalline alloy ribbons Fe40Co4oZr9-yMyB1oGe1(y = 0-4;M = Nb,Mo)were prepared by crystallizing the as-quenched amorphous alloys.The effects of Nb and Mo additions on structures and properties of the Fe40Co40Zr9B10Ge1 alloy are investigated system-ically and compared.With increasing Nb or Mo content,the primary crystallization temperature,grain size of α-Fe(Co)phase and coercivity Hc all decrease.Moreover,the effect of Mo addition on thermal behavior,microstructure and magnetic properties of the FeCoZrBGe alloy is greater compared to Nb addition.The gap between primary and secondary crystal-lization peaks of Mo-containing alloys is wider than that of Nb-containing alloys.Both grain size and Hc of Mo-containing alloys are smaller than those of Nb-containing alloys.For Fe40Co40Zr9B10Ge1 alloy,high Mo addition proportion is better compared to high Nb addition proportion.
