S., Registration Date 10-12-2003 Organization Frantzevich Insitute for Materials Science Problems of the Ukranian National Academy of Sciences popup.description2 The mechanisms of the structural-phase transformations proceeding in monophase powder systems (BNg and BNsp) and compositions (BNg+diamond, BNsp+diamond, BNw+diamond, and BNg+graphite) during sintering under high pressure were studied. It was established that recrystallization was the determining process in the formation of the structural state of the materials. It is shown that the granular structure of the materials can be controlled by changing sintering parameters (P,T, and time). Product Description popup.authors popup.nrat_date 2020-04-02 Close
