Abstract

The possibility is shown to decrease the cost of production of powder hot-deformed carbon steels through the use of unconventional carbon-containing components in the charge composition (artificial special low-ash graphite, pyrocarbon, high-temperature coal-tar pitch). The peculiarities of their chemical composition, grain-size distribution, and crystal structure in comparison with the traditionally used pencil lead dictate the increase in blend homogeneity and in density of cold-pressed moldings, and eventually improvement of properties of powder steels.
