Aluminium matrix composites have become increasingly important in recent years due to their superior mechanical and chemical properties. The combination of an aluminium light metal matrix with carbon nanotubes (CNT) enables good fatigue and fracture properties, high thermal and electrical conductivity, increased hardness, and good impact and wear resistance of the composite. Liquid state processes are suitable for the production of large and complicated components, e.g. structural components. So far, the very large specific surface area and high interfacial energy of CNTs offers a high potential for agglomeration and poor distribution for liquid state processes. The aim of this work was to investigate the influence of a novel two-step melt metallurgical processing method on the incorporation of CNTs in the Alluminium-Matrix, respectively on the yield strength and the elongation. The approach consists of the advantages of UST treatment either with the support of the increased shear forcees in semi-solid state and/ or with a predispersion of the CNT with aluminium powder. The results indicate both the largest increase in yield strength and elongation for the AL-CNT incorporating the predispersed powder mixture in the semi-solid range. An increase in yield strength of 135 % and elongation of 275 % were achieved compared to the unreinforced alloy.
