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.

“…Traditional methods, such as forging, extrusion, and rolling, have been applied to producing the Mg alloy tubes, sheets, and strips. Now the processing of metals through severe plastic deformation (SPD) is attracting considerable interest, due to SDP's ability to create intense plastic strain without introducing changes to the dimensions of work pieces (Dong et al, 2021;Gunderov et al, 2021;Ren et al, 2021;Zhao et al, 2021;Roghani et al, 2022). Furthermore, a number of recent publications demonstrate that SPD techniques are capable of producing materials possessing ultrafine grain sizes within the submicrometer or nanometer range, as well as both high strength and ductility (Kasaeian-Naeini et al, 2021).…”

The microstructural, textural, and mechanical effects of high-pressure torsion processing on Mg alloys: A review

Magnesium (Mg) alloys attract considerable attention in the fields of aerospace, defense technology, and automobile production, owing to the advantages of their low density, their highly specific strength/stiffness, and their good damping and electromagnetic shielding performance. However, low strength and poor ductility limit further application. Severe plastic deformation is considered the most promising means of producing ultrafine-grained Mg alloys and improving their mechanical properties. To this end, high-pressure torsion (HPT) is one of the most effective techniques. This article outlines the microstructure, texture, and mechanical properties of Mg alloys processed using HPT. The effects of deformation parameters, such as processing temperature, turns, applied pressure, and rotation speed, on the grain refinement and secondary phases are discussed. Textural evolution is detailed in light of both intrinsic and extrinsic factors, such as cumulative strain and the composition of the alloy elements. The subsequent enhancement of mechanical properties and mechanisms, and the significant contribution of the HPT process to strength are further reviewed. Given the advantages of HPT for grain refinement and structural modification, researchers have proposed several novel processes to extend the industrial application of these alloys.
