摘要

General formula: Fe _100-xyz A _x B _{y X z} where (, A is Cu and Au or /, X is at least one selected Si, S, C, P, Al, Ge, from Be and Ga is an element, x, z and y is a composition represented by.) is a satisfying number of x + y + z ≦ 25 and 22,0 ≦ z ≦ 10, 0 x ≦ 5,10 ≦ y ≦ by atomic% and a has a tissue initial super-fine crystal grains of 30 nm or less average particle diameter are dispersed at a ratio of 5 to 30% by volume amorphous phase Shitsuhaha, (DSC) curve of the crystalline differential scanning calorimetry and an exothermic peak of the second exothermic peak is smaller than the first and the exothermic peak of the first between the compound deposition temperature T _X3 and starting temperature T _X1, the heat generation of the second and the exothermic peak of the first Initial ultrafine crystal alloy ratio of the heating value of the exothermic peak of the second to the total heating value of the peak is 3% or less.
