摘要：
An attempt is made to decrease expenditures for production of powder steels via use of nontraditional metallurgic wastes in burden: artificial special low-ash graphite and pyrocarbon. It is shown that peculiarities of chemical and granulometric compositions and crystal structure of these components induce an increase in the burden homogeneity and the cold-pressed molds density, acceleration of the material homogenization during sintering, improvement of the material structure and properties.
