摘要：
The effect of the content of manganese silicide (MnSi1.77) additive in the original charge and sintering temperature on the structure and properties of sintered steels is investigated. It is shown that adding manganese silicide slightly decreases the density of sintered samples, but significantly increases the hardness and strength properties of the alloys. An electron microprobe analysis of sintered steels establishes that manganese is relatively uniformly distributed in iron particles, whereas the distribution of silicon is significantly different: its higher concentration is mainly seen along the grain boundaries.
