The effect of Cu addition on the microstructure and low-temperature magnetization of nanocrystalline Fe87-xZr7B6Cux and Fe81-xZr7B12Cux alloys

Abstract

The microstructure and low-temperature magnetization of nanocrystalline Fe87-xZr7B6Cux and Fe81-xZr7B12Cux alloys (x = 0, 1 and 2 at.%) have been studied using a combination of differential scanning calorimetry, x-ray diffraction analysis, transmission electron microscopy and superconducting quantum interference device magnetometry. The results show that the substitution of 1 at.% copper for iron in both low- and high-boron-content alloys has significant effects on the microstructure and magnetic properties, while increasing the copper content to 2 at.% does not cause any further significant change in the microstructure and magnetic properties. For the low-boron-content alloys, the addition ..
