Abstract

In the present work, wet ball milling and spark plasma sintering were used to develop carbon nanotube (CNT) reinforced Al6061 and Al2124 nanocomposites which have potential applications in aerospace and automotive industries. Al6061 and Al2124 nanocomposite powders containing 1 and 2 wt. % CNTs prepared through sonication and wet ball milling were spark plasma sintered at 400, 450, and 500 °C for 20 minutes under a pressure of 35 MPa. In case of 1 wt. % content, CNTs were found to have better dispersion and less agglomeration. The increase of CNT content to 2 wt. % resulted in formation of CNT clusters and hence their inhomogeneous distribution across the matrix. Composites reinforced with 1 wt. % CNTs displayed better densification compared to composites containing 2 wt. % CNTs. However, almost full densification was achieved for both composites at 500 °C. Maximum hardness was found for composites containing 1 wt. % CNTs. For composites containing 2 wt. % CNTs, hardness was found to be lower than that of the monolithic alloys.
