Sintered manganese steels produced using copper-bearing ferromanganese master alloy
The paper examines the properties of sintered manganese steels produced with the use of copper-bearing ferromanganese master alloys depending on the master alloy content and sintering temperature. It is shown that increase in the master alloy content promotes higher strength and hardness. The interaction of master alloy particles with the matrix material is accompanied by much more uniform distribution of copper in the grain as compared with manganese, whose inclusions are mainly distributed at the boundaries of iron powder particles.
