摘要
Local structures of the mechanically alloyed Fe_(77-x)Ni_(x)Cu_(1)Nb_(2)P_(14)B_(6)soft magnetic materials have been in vestigated by x-ray absorption fine structure.The results show that mechanical alloying(MA)can drive theFe_(77-x)Ni_(x)Cu_(1)Nb_(2)P_(14)B_(6)powder mixture to produce amorphous alloy when the atomic concentration of Fe ele ment is about and over 40%.On the contrary,the MA Fe_(77-x)Ni_(x)Cu_(1)Nb_(2)P_(14)B_(6)is a solid solution with an fcc-like structure in the region of lower Fe atomic concentration(<22%),preserving a medium-range order around Ni and Fe atoms.Moreover,we have found that the local structure geometry of Fe atom is similar to that of Ni atom for all the MA Fer7-xNixCu1 Nb2P14B6 samples.It indicates that the local structures of Fe and Ni atoms in a Fe_(77-x)Ni_(x)Cu_(1)Nb_(2)P_(14)B_(6)sample only depend on the x value of element Ni after ball milling.
