Aluminum alloys are of special interest to be used a matrix in composites due to their low specific weight, which is why they are very popular in the aeronautic and aerospace industry, especially the 2xxx, 6xxx, and 7XXX series, which can be heat treated in order to improve their strength. Among the mentioned alloys, the 7XXX series, whose main alloying elements are Zn and Mg, exhibit the greatest response to the precipitation hardening, thus, the AA7075 is considered a high strength alloy because its yield strength is above 500 MPa in the optimal aging conditions [5,6]. This fact has motivated the investigation about how AA 7075 can be modified by introducing nanoparticles of partially yttria-stabilized Zroz (hard and chemically stable ceramic) with the aim to obtain adequate oxide dispersion strengthening (oDs by using ball milling processes. the aim to Previous studies have used Zro2 as reinforcement with improve the properties ofthe alloy. Fuentes-Ramirez et al. [7]improved the wear resistance of pure Al, using a surface treatment employing
