摘要：

The present paper investigates the effect of carbon nanotube (CNT) length (including the use of short multi-wall CNTs) and milling parameters on the nickel matrix crystal size, dislocation density, micro-strain, and CNT integrity post milling of mechanically milled Ni-CNT composite powder. Results show that CNT integrity is independent of CNT length post milling and short CNTs interact differently during milling resulting in more refined matrix microstructures, increased strain and dislocation density within the milled Ni-CNT powders compared with longer CNTs. The Ni-CNT powders were also preliminarily investigated as precursors in the reactive processing of nickel aluminide-CNT composites. Compacts with short CNTs resulted in better reaction characteristics producing composites with more Ni3Al content and greater hardness than reacted compacts with larger CNTs.
