The study of structure of Fe–B–P based metallic glasses
2013
Abstract Rapidly quenched (RQ) Fe–B–P alloys with addition of Co and Cu exhibit excellent soft magnetic and mechanical properties. A system of the type (Fe 85− z Co z B 15 ) 100− x − y P x Cu y with x = 3, 4, 5; y = 0, 1 and z = 0, 21 at.% has been prepared by planar flow casting in form of thin ribbons. Selected properties in as-cast state and after controlled annealing targeted to produce fine-grain structure were determined. The effect of the substitution of Fe for Co and the additions of P and Cu on structure in nanocrystalline state was investigated. These systems were investigated by thermogravimetry (TGA) and by differential scanning calorimetric (DSC) measurements. The structure was investigated by XRD and TEM (HREM).
