Synthesis and Densification of Nanomaterials by Mechanical and Field Activation
Tóm tắt
The use of mechanical and electric field activation to simultaneously synthesize and densify nanomaterials was investigated. Dense nanostructured MoSi2 and TiN-TiB2 nanocomposites were made by this method. The role of the parameters of mechanical activation (milling) and those of field activation on the process of formation of dense nanomaterials was studied. For the TiN–TiB2 system, up to 97.2% dense nanocomposites were synthesized with microhardness and fracture toughness values of 21.8 GPa and 5.13 MPa•m1/2, respectively.
