“…There have been many reports on the influence of plastic deformation on the precipitation process [16,[20][21][22][23]. As a representative work, the cyclic strengthening (CS) method proposed by Sun et al introduces dislocations and accelerates the diffusion of solute atoms to form nanoclusters by applying periodic, reciprocating plastic deformation, thereby greatly improving the strength [16].…”

Aging heat treatment is the most commonly used strengthening method for Al–Mg–Si alloys since high-density precipitates will be formed to hinder the movement of dislocations. In the current work, room temperature cyclic deformation was attempted to strengthen the alloy. We compared tensile test results of aged samples and cyclically deformed samples. It was found that cyclically deformed samples can achieve similar strength and approximately twice the uniform elongation as the peak aged samples. The high density of dislocations and nanoclusters observed in the cyclically deformed samples is thought to be the main reason for strengthening. Different cyclic deformation conditions have been tried and their effects were discussed.

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. SEM, TEM, and EDS-MAP analyses, tensile strength, microhardness, and Pin-on-Disc tests were performed to study the ARB-ed sheets. The results of the tensile tests showed that the tensile strength of AA2024-AA1050 created by the six stages 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 to improvement in tensile strength and total elongation of AA2024-AA1050/Al2O3 nanocomposites.
