Hybrid Static-Dynamic Technology for Compaction of a Powder Composition inside a Metal Shell

The paper considers three possible schemes for implementing the hybrid technology of compacting a powder composition inside a deformable metal shell: sequential execution of operations “drawing – pulse-magnetic crimping”, sequential execution of operations “pulse-magnetic crimping – drawing”. The third scheme assumes the simultaneous execution of these operations, for implementation of which a design of a ceramic drawing die with a built-in current conductor of the inductor, connected to a pulsemagnetic installation, is proposed. A technique of computer simulation of the hybrid static-dynamic technology for compaction a powder composition inside a deformable tubular shell has been developed for all three schemes. Using it, visualization pictures of the processes have been obtained, which gives a qualitative idea of the mechanism (features) of compaction, of the infl uence of deformation-force parameters of the process on the packing density of the powder composition. An analysis of each of the proposed schemes, their advantages and disadvantages are given, which ensures their justifi ed choice depending on the specifi c technical task when obtaining a composite material and structures from it.
