“…This strain causes work hardening and creates a high density of dislocations. In 2024 layers, intrinsic precipitates such as T-phase (Al 20 Cu 2 Mn 3 ), Al 77 Cu 10 Fe 7 Mn 5 Si 2 , Al 79 Cu 13 Fe 5 Mn 2 Mg 0.7 Si 0.2 , and Al 65 Cu 17 Mg 18 also play a significant role [ 23 , 31 ]. During rolling, differences in the flow of the metal matrix and precipitates cause dislocations at the boundary between the precipitates and the metal matrix (Fig.…”

“…Also, this study used Al 2 O 3 nanoparticles (purity of more than 98% and particle size less than 100 nm) as reinforcement. Initially, the particles were agglomerated but separated by successive rolling [ 23 ]. Figure 1 shows the XRD and SEM analysis of these nanoparticles.…”

“…The reason for this is the layered structure of the ARB-ed sheet and the increase in the mechanism of delamination during wearing. Creating a composite with ceramic reinforcement particles may improve wear resistance [ 4 , 23 ].…”

We created AA2024–AA1050 and AA2024–AA1050/0.005 vol.% Al2O3 nanocomposites by six accumulative roll bonding (ARB) process cycles. We used AA2024 and AA1050 sheets with a thickness of 0.7 mm and plate-shaped alumina nanoparticles to create a composite. The two AA1050 and one AA2024 sheets (among the two AA1050 sheets) were ARB-ed up to six cycles with and without adding alumina nanoparticles. Also, a sample of the AA1050 without composite making was ARB-ed up to six cycles. We aged some composites after the ARB process in the furnace at 110, 150, and 190 °C. This project performed SEM, TEM, and EDS-MAP analyses, tensile strength, microhardness, and Pin-on-Disc tests to study the ARB-ed sheets. The results of the tensile tests showed that the tensile strength of AA2024–AA1050 created by the six cycles ARB process was two times more than primary AA1050. Also, the wear resistance of this composite was 74% more than six cycles ARB-ed the AA1050. Using 0.005 vol.% alumina nanoparticles in AA2024–AA1050 composite improved its wear resistance by 30%. In the following, the aging process caused an improvement in tensile strength and total elongation of AA2024–AA1050/Al2O3 nanocomposites.

“…The harder layer is crushed in layered composites due to the slow strain. However, the soft layers remain continuous due to the high strain rate [16][17][18]. Adding reinforcement particles in the early cycles of ARB can create a metal composite and reinforcing particles.…”

We created AA2024-AA1050 and AA2024-AA1050/0.005 vol.% Al2O3 nanocomposites by six accumulative roll bonding (ARB) process stages. AA2024 and AA1050 sheets with a thickness of 0.7 mm were used to create a composite. Also, plate-shaped alumina nanoparticles were used in the composites. The two AA1050 and one AA2024 sheets (among the two AA1050 sheets) were ARB-ed up to six cycles with and without adding alumina nanoparticles. Also, a sample of the AA1050 without composite making was ARB-ed up to six cycles. Some composites were aged after the ARB process in the furnace at 110, 150, and 190°C.
