“…For metal powder, density is further improved up to 96% of the cast value by MPC at the maximum voltage. Uniform and fine microstructure formed in the alloy powders as atomised is almost maintained even after thermal MPC [ 37 ]. Some theoretical and experimental studies on the magnetic pulse compaction of nanosized powder have been carried out.…”

“…In addition to theory and experiment, finite-element (FE) simulation analysis is an effective method for the preliminary exploration of new process schemes for self-prepared conductive Graphene/PEKK composite powders [ 40 , 41 , 42 ]. Some studies have been performed on the electromagnetic pulse compaction FE analysis method of metal and metal-composite ceramic powder [ 36 , 37 , 38 ], but almost no research has been conducted on electromagnetic pulse compaction of self-prepared conductive Graphene/PEKK composite powder.…”

Polymer-composite materials have the characteristics of light weight, high load, corrosion resistance, heat resistance, and high oil resistance. In particular, graphene composite has better electrical conductivity and mechanical performance. However, the raw materials of graphene composite are processed into semi-finished products, directly affecting their performance and service life. The electromagnetic pulse compaction was initially studied to get the product Graphene/PEKK composite powder. Simultaneously, spark plasma sintering was used to get the bars to determine the electrical conductivity of Graphene/PEKK composite. On the basis of this result, conducting Graphene/PEKK composite powder can be processed by electromagnetic pulse compaction. Finite element numerical analysis was used to obtain process parameters during the electromagnetic pulse compaction. The results show that discharge voltage and discharge capacitance influence on the magnetic force, which is a main moulding factor affecting stress, strain and density distribution on the specimen during electromagnetic pulse compaction in a few microseconds.
