Notes:
Machinable BN/Si3N4 and electroconductive TiN/Si3N4 nanocomposites were prepared, usingpowders synthesized through an in-situ nitridation method in flowing ammonia gas. Due to thehomogeneous mixing of various components in the powders, nanocomposites with homogeneous secondphase distribution in the matrix were obtained. These nanocomposites showed enhanced strengths anddistinctive functionalities. BN/Si3N4 nanocomposite with 20-25vol% BN showed a relatively highstrength of over 700 MPa and was able to be machined into complicated shapes with diamond bits.Electroconductive TiN/Si3N4 nanocomposite with 25vol% TiN showed a high strength of 1100MPa andlow electrical resistivity of 1.1×10-2 [removed info]⋅cm, and was promising for electrical discharge machining
