Studies of X-ray amorphous phase in mechanochemical synthesis of iron silicides from elements

Iron disilicide synthesis was developed by means of mechanochemical activation under intensive mechanical treatment. The Xray amorphous phases formed during mechanical treatment of initial iron and silicon were investigated. The methods of the differential dissolution, differential thermal analysis and X-ray phase analysis were used. The formation of supersaturated amorphous solid solution of silicon in iron with limited concentration 17 at.% Si takes place during the initial period of activation. Primary phase obtained in this system is iron monosilicide formed in the decomposition of amorphous supersaturated solution.
