Sintered Manganese Steels Produced with Copper-Containing Ferromanganese Master Alloy

Abstract

The paper examines the properties of sintered manganese steels produced with the use of copper-bearing ferromanganese master alloys depending on the content of the master alloy and sintering temperature. It is shown that increase in the content of the master alloy 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.
