. Powder metallurgy is an effective way to produce a variety of high performance structure materials[6], materials under extreme conditions and special function materials; and it can also achieve near-net-shape powder products[7]. It is effective to produce high relative density powder products by using high strength impact loading[8], one of which is dynamic magnetic compaction (DMC, namely magnetic......
