Specific features of the use of unconventional carbon-containing components in the technology of powdered steels: Report 2. The influence of unconventional carbon-containing components on the sintering processes in the technology of powdered steel

The processes of sintering powdered carbon steels with the introduction of unconventional carbon-containing components into the charge (special artificial low-ash graphite, pyrocarbon, and high-temperature coal-tar pitch) are considered. It is shown that the features of the chemical and granulometri...

Description
Summary:The processes of sintering powdered carbon steels with the introduction of unconventional carbon-containing components into the charge (special artificial low-ash graphite, pyrocarbon, and high-temperature coal-tar pitch) are considered. It is shown that the features of the chemical and granulometric compositions and the crystalline structure of these components (to a greater extent than the conventionally used pencil lead) determine the acceleration of material homogenization during sintering, improve its structural characteristics, and increase its mechanical properties.
