Os nanocomp?sitos de matriz met?lica ? base de alum?nio (MMNCs) est?o ganhando popularidade nas ind?strias automotiva, aeroespacial e mar?tima devido ao seu peso leve, alta resist?ncia e excelente resist?ncia ao desgaste. Neste estudo, a liga AA 7075 foi usada como material de base e refor?ada com ?xido de alum?nio de tamanho nano (Al?O?), carboneto de sil?cio (SiC) e uma quantidade fixa de magn?sio (1 wt.%) para melhorar a molhabilidade. Estes refor?os foram adicionados em percentagens de peso vari?veis (1%-4%) utilizando o m?todo de fundi??o por agita??o, que assegura uma distribui??o uniforme das part?culas e reduz a porosidade. A an?lise microestrutural confirmou uma dispers?o maioritariamente uniforme das part?culas, enquanto os testes mec?nicos mostraram que a adi??o de refor?os melhorou significativamente a dureza, a resist?ncia ? tra??o e a resist?ncia ao desgaste, embora a ductilidade tenha diminu?do ligeiramente. Os comp?sitos h?bridos (Al?O? + SiC) tiveram melhor desempenho do que aqueles com refor?os ?nicos. No geral, o estudo demonstra que os nanocomp?sitos AA 7075 fundidos por agita??o oferecem propriedades aprimoradas e s?o adequados para aplica??es de engenharia de alto desempenho.
