Mechanical alloying (MA) of elemental powder mixtures of Fe 50 Nb 35 C 15 , Fe 60 Nb 30 C 10 and Fe 50 Nb 40 C 10 was performed using a high energy ball mill. In the MA processing, ball milling first leads to a Fe-Nb-C amorphous phase and nanocrystalline NbC. Further milling results...
Nanometer size TiC particulate reinforcements were in situ synthesized in Ti matrix composites under high pressure and high temperature conditions. The relationship between the mean grown sizes of TiC and the processing conditions, as well as its mechanism, is discussed. The microhardness of these composites was measured.
