An effective-medium type method is developed for the effective magnetostriction of nanocrystalline magnetic alloys based on the successful Green's function technique recently developed for magnetostrictive composites. A more general, explicit relation for determining the effective magnetostriction of nanocrystalline alloys is derived, and it recovers those previous Reuss-type approximations in the special cases. For illustration and comparison, calculations for the effective magnetostriction of nanocrystalline Fe85Zr7B6Cu2 alloy are given. The effective-medium type formula is more applicable to consider the interfacial effect.
