Amorphization and evolution of magnetic properties during mechanical alloying of Co62Nb6Zr2B30: dependence on starting boron microstructure
Description
Co62Nb6Zr2B30 composition was mechanically alloyed using three different types of boron
powders in the starting mixture: crystalline β-B, commercial amorphous B and optimized
amorphous B via ball milling. Using optimized amorphous B, amorphization process of
the alloy is more efficient but milling to optimize amorphous B introduces some iron
contamination. Boron inclusions (100-150 nm in size) remain even after long milling
times. However, using amorphous boron reduces the fraction of boron distributed as
inclusions to ~40% of the total B. Thermal stability at the end of the milling process is
affected by the initial boron microstructure. Coercivity is reduced a half using amorphous
B instead of crystalline B in the starting mixture
