Abstract
The influence of dispersed microadditives of different nature on bulk changes during sintering and strength of powder carbon and high-chromium steel is investigated. Mechanisms of the influence of additives on their structure formation are described. It is shown that the largest hardening of carbon steel is provided by the introduction of sodium bicarbonate, while of high-chromium steel – of boron nitride additives. The level of hardness increase depends on the sintering temperature and additive amount.
