Aluminum Alloy Sheet

This paper presents the main achievements of a research project aimed at investigating the applicability of the hot stamping technology to non heat treatable aluminium alloys of the 5052 H32 and heat treatable aluminium alloys of the 6016 T4P after six months natural aging. The formability and mechanical properties of 5052 H32 and 6016 T4P aluminum alloy sheets after six months natural aging under different temperature conditions were studied, the processing characteristics and potential of the two aluminium alloy at room and elevated temperature were investigated. The results indicated that the 6016 aluminum alloy sheet exhibit better mechanical properties at room temperature. 5052 H32 aluminum alloy sheet shows better formability at elevated temperature, and it has higher potential to increase formability by raising the temperature.

Initial Delay

Abstract The fire performance of several types of wood-aluminum composites (WAC) was analyzed by the small vertical furnace test. The time needed to reach the temperature of 139°C/181°C (T139°C/181°C) and the linear char rate of 300°C (L300°C) were obtained by evaluating the fire performance of WAC. The T139°C/181°C values ranged from 23.6 to 44.8 min. The presence and position of the aluminum alloy sheet remarkably affected the fire performance of WAC. In addition to an initial delay of 19 min, the L300°C also increased when the aluminum alloy sheet was located on the surface. However, the times for 300°C only increased slightly when the aluminum alloy sheet was in the middle. The initial delay observed for the aluminum alloy sheet on the surface was reduced by more than 50% when the wood veneer was located on the surface of the aluminum alloy sheet. The mechanical properties of WAC were also investigated. It was concluded that the uniformity and strength of different composites was improved after the lamination of the aluminum alloy sheet. In addition, the modulus of elasticity of WAC quadrupled, and the bonding strength between the aluminum alloy sheet and the oriented strand board (OSB) was greater than that of the OSB.

Abstract A multi-layered complex aluminum alloy was successfully fabricated by three-layer stack accumulative roll bonding(ARB) process. The ARB using AA1050 and AA5052 alloy sheets was performed up to 7 cycles at ambient temperature without lubrication. The specimen processed by the ARB showed a multi-layer aluminum alloy sheet in which two aluminum alloys are alternately stacked. The grain size of the specimen decreased with the number of ARB cycles, became about 350nm in diameter after 7cycles. The tensile strength increased with the number of ARB cycles, after 6c it reached 281MPa which is about twice higher than that of the starting material. The microstructures and mechanical properties of a three-layer AA1050/AA5052 alloy fabricated by the ARB were compared to those of the conventional ARB-processed material.

In this paper, it was aimed to develop a new Al-Zn-Mg base aluminum alloy having high electrical conductivity, strength, and formability simultaneously. As a result, Al-Zn-Mg base low aluminum alloy sheet can be effectively strengthened without significant thermal conductivity loss by multiply alloying precipitation hardening elements and properly controlling production process parameters.

Recently, friction stir processing (FSP), as an effective tool, has been employed to modify microstructures and mechanical properties of metal sheet. A novel technique of double surface friction stir processing (FSP) was proposed in this study. A 7050-T7451 aluminum alloy sheet of 6.5mm in thickness was processed by FSP with 30% overlap in each side. The position deviation of the stir pin from the upper surface to the bottom surface is 35%. Significant grain refinement with an average grain size of 2.5μm from the as-received 50μm, can be obtained after double-sided FSP. In comparison with the conventional FSP, no HAZ (heat affected zone) or TMAZ (thermal mechanical affected zone) was formed between the adjacent stir zones of the aluminum alloy sheet. At a strain rate of 10-3 s-1, a maximum elongation of 29.8% and 327% in transverse direction of FSP passes have been achieved at room temperature and 400°C, respectively.
