    Carbon Nanotubes (Cnt) Are Promising Materials To Strengthen Lightweight Aluminum Matrix Composites, But Their Dispersion Into The Metallic Matrix Is Challenge, Such As The Difficulty Of A Obtaining A Homogeneous Dispersion Of The Cnt Into The Matrix And The Maintenance Of Its Integrity During The Processing Conditions. In The Addition, Addition Of Cnt May Modify The Heat Treatment Cycle. This Study Aimed To Analyze The Influence Of Milling Time And Heat Treatment On The Mechanical Properties Of Aa6061 Aluminum Alloy Matrix Composites Reinforced By Multi Walled Carbon Nanotubes (Mwcnt). The Composites Were Previously Fabricated By Powder Metallurgy Route: Mechanical Alloying (6 And 10 Hours) And Subsequently Hot Extrusion. Mwcnt Are Added Under Different Conditions: Untreated, Functionalized And Functionalized And Decorated With Ag, In 1, 2 And 4% By Weight. Samples Were Also Produced With No Reinforced Addition (Reference Sample) For Comparison Purposes. The Composites Were Analyzed Under The Conditions As E
