Abstract:
The work is dedicated to obtaining a complex Al-Mn-Fe master alloy for precise alloying high-manganese steels with aluminum high content as well as for making additions during aluminum alloys production. The addition of aluminum large quantity to steel during steelmaking is an especially difficult task, because of the low density and melting temperature of aluminum. [..]

Abstract:
Non-metallic inclusions are one of the factors that influence the fatigue strength of steel. Although steel has a relatively small number of non-metallic inclusions, those impurities have a considerable impact on the material's technological and strength parameters, in particular fatigue strength and life.
