چکیده انگلیسی
Cu matrix composites reinforced with 0-3â¯wt% CNTs are fabricated via molecular-level mixing, microwave sintering and rolling technology. A homogeneous distribution of CNTs is exhibited in copper matrix. Clean CNTs/Cu interfaces perform high bonding strength. Electrical conductivity and relative density of microwave sintered CNTs/Cu composites decrease with increase in CNTs content. There exists maximum for hardness of CNTs/Cu composites which rise and then fall with the rise of CNTs content. When CNT contents are less than 1â¯wt%, it provides a good control over microstructures with low porosity and small pore size. Subsequent rolling process enables better microstructure and performance of sintered composites which shows tensile strength of 218â¯MPa, the elongation of 37.75%, and the electrical conductivity of >98% IACS compared to pure copper. Our studies provide a robust approach to high-performance CNTs/Cu composites by microwave sintering.
