FIELD: metallurgy.
SUBSTANCE: functional gradient item (20) from composite material with metal matrix (CMM) has solid central layer (18) enriched with solid particles (10) enclosed between external covers (6, 8). Item is obtained by supplying the molten metal (M) containing solid particles (10) to a pair of moving casting surfaces (D1, D2), curing of molten metal (M) and removing of item (20) from CMM from the gap between casting surfaces (D1, D2). Solid central layer (18) has higher concentration of solid particles (10) than any of external layers (6, 8).
EFFECT: item from composite material with metal matrix combines easy metal processing and improved mechanical properties.
