Mechanosynthesis of Precursors for TiC–Cu Cermets
- 20 Downloads
The structural and phase state of the samples obtained by co-grinding of Ti and Cu powders under different conditions (with graphite, in petroleum ether, and in xylene) is investigated. It is demonstrated that after thermal treatment of powders obtained by milling of titanium, copper, and graphite in petroleum ether, both cubic titanium carbide and hexagonal titanium carbohydride are formed, whereas by milling without graphite, only hexagonal carbohydride possessing high thermal stability is formed. CuTi and CuTi2 intermetallic phases are formed under all examined conditions of mechanosynthesis.
