FIELD: metallurgy.
SUBSTANCE: there is disclosed melt of following composition, wt %: aluminium 26.0-32.0, carbon 0.86-1.30, iron - the rest. Melt is poured with thickness 1-2 mm on surface of iron sheet, cooled to room temperature and crushed to lumps. Lumps are placed into a steam chamber with temperature over 100°C and humidity 15-20 % and conditioned during 1-2 hours. Further, they are cooled to room temperature producing powder in form of super-dispersed particles of 102-103 nm size.
EFFECT: simplified process of production of composite nano dimension powder of high adhesion property to gases in metal melts with modifying capacity for cast iron and silumin and increased mechanical strength.
