They relied on high-energy ball milling and powder compaction either via ECAP or hot extrusion. Different processing parameters were used in order to break the clusters of NPs and to improve the final properties of the composites. The

A ball-to-powder weight ratio r = 5:1 was adopted for grinding the metal powder for 5 h using 10 % of ethanol as PCA. Consolidation of powder was performed by ECAP, by hot extrusion and by combining the two process. ECAP was also used fo

In particular, it was understood that high-energy ball milling was not able to completely break up the large alumina clusters. In the following experiments, an isopropanol colloidal solution of alumina nanoparticles was

So far, better dispersion was achieve by using colloidal solution of γ-Al.O. nanoparticles in isopropyl alcohol than by using dry-Al.O.. Thus, the composites were prepared again by adding 2 wt% of colloidal alumina to the Al powde
