Synthesis and liquid phase sintering of TiN/TiB2/Fe–Cr–Ni nanocomposite powder
نویسندگان
چکیده
Nanostructured TiN/TiB2/Fe–Cr–Ni composite powder has been prepared via high energy ball milling. Ti and BN powders are reacted to form uniform mixture of TiN and TiB2 within 2 h of milling by a mechanically activated self-sustaining reaction (MSR). The crystallite sizes of TiN nd TiB2 are about 7 and 16 nm, respectively, after 32 h of milling. Through liquid phase sintering and optimizing the milling time, a compact body ith almost full density could be obtained which has a narrow grain size distribution and exceptionally high hardness. 2005 Elsevier B.V.

متن کاملMechanically Activated Combustion Synthesis of B4C-TiB2 Nanocomposite Powder
Boron carbide is one of the hardest materials. The combustion method was used to synthesize B4C-TiB2 nanocomposite powder in a B2O3-Mg-TiO2-C system. An experimental study of the formation of B4C–TiB2 nanoparticles was conducted in the thermal explosion mode. A mixture of B2O3:TiO2:Mg:C at a molecular ratio of 3:1:12:1 was chosen to obtain the B4C–TiB2. This powder mixture was milled for differ...
