Fecha de publicación: | 2014 | Editor: | Elsevier | Citación: | Journal of Alloys and Compounds, 615S1 (2014) 552-555 | Resumen: | Microstructure and magnetic properties of metalloid-free (Fe100- xCox)90Zr10 amorphous and nanocrystalline alloys were characterized. Devitrification of these amorphous alloys occurs in two overlapped transformations leading to the formation of α-Fe(Co) and Fe(Co)Zr2 phases. Constant local Avrami exponents have been found for each individual process. Although Co-free alloy shows a larger grain size, crystalline fractions are similar for both alloys after equivalent annealing. Good soft magnetic properties at room temperature have been observed for amorphous and nanocrystalline alloy with x = 30, which exhibits an amorphous Curie temperature of 735 K. The x = 0 amorphous alloy is paramagnetic at room temperature and nanocrystalline samples exhibit a transition to superparamagnetic behavior | Versión del editor: | http://dx.doi.org/10.1016/j.jallcom.2014.01.095 | URI: | http://hdl.handle.net/10261/103561 | DOI: | 10.1016/j.jallcom.2014.01.095 |
