Abstract:
Phase composition of the materials obtained by mechanical alloying of system Co–Al (Al concentration ranges from 50 to 70 at.%) and removal of aluminum from such alloys was investigated by differential dissolution, X-ray phase analysis and TEM with a resolution of 0.4 nm. The intensive mechanical alloying provides formation of the nanocomposite material containing both amorphous phase Co2Al5 and nanocrystalline particles of phase CoAl. Leaching of amorphous phase Co2Al5 results in the amorphous cobalt containing admixtures of alumina and hydroxide. Nanocomposite amorphous phase Co2Al5 and CoAl convert into nanocomposite amorphous Co and b.c.c. Co.
