Electromagnetic powder compaction technology is an effective method for producing high density and strength parts. In this work, the influence of discharge energy on the electromagnetic compaction characteristics of copper powders with same compression amount was studied through experiment investigation and numerical simulation. The finite element simulation, micro morphology observation, and compressive strength testing were conducted. Results showed that the propagation direction of stress was 45 degrees from top to bottom of compacts. At 7-9 kJ, there was a turning phenomenon in the directi...
