Sintering of powder mixtures and the growth of ferrous powder metallurgy

Advances in the understanding of sintering of powder mixtures contributed significantly to the growth of ferrous powder metallurgy industry. Solid-state sintering and liquid-phase activated sintering play an important role in the sintering of powder mixtures. In this paper, sintering of iron powder with graphite; iron powder with copper and graphite; iron powder with nickel and graphite; iron powder with phosphorus; and iron powder with boron is discussed. Mechanical properties of the sintered parts are presented along with application of these parts.
