FIELD: chemistry.

SUBSTANCE: invention relates to production of composite metal plate with pattern. Method includes steps of: a) providing powders of at least two different metals and/or metal alloys; b) filling container: b1) with powders in different individual layers, wherein individual layers of powders include at least two non-parallel layers and/or non-rectilinear layers; or b2) manufacture of a three-dimensional discontinuous body from one of the powders, which includes at least two non-parallel sections or layer, and/or non-straight sections or layer; placing said body in container and filling cavities in said body and around it with another powder; c) sealing and evacuation of container; d) performing isostatic pressing of the container to form a single body, comprising non-parallel and/or non-straight layers of metals and/or metal alloys; e) it is possible to perform hot deformation of a single body to form an intermediate body having thickness of 50 to 200 mm; f) hot rolling of a single or intermediate body in two perpendicular directions to form a plate; possibly, one or more stages of g) cold rolling of hot-rolled plate, for formation of cold-rolled plate; h) lengthwise cutting of the plate into two or more parts; and i) etching the plate to detect or reinforce the pattern.

EFFECT: enabling production of composite metal plate with pattern.
