In order to lower fuel consumption and reduce emissions, aluminum is being considered as an alternative to steel in large scale production of autobodies. This study evaluates the prospects of aluminum sheets as a cost efficient alternative to steel in autobodies with the unibody design. The study focuses on the processing technologies and alloy selection for aluminum automotive sheets and looks...

Compared with the conventional manufacturing of aluminum sheet metal, the forming of so called Tailored Heat Treated Blanks (THTB) enables the production of complex aluminum sheet metal parts [1], [2]. The reasons for the lower forming behavior of aluminum alloys are well founded in the material properties. Especially smaller values for uniform elongation (< 30 %) and vertical anisotropy (< 1) ...

the cold roll bonding of al on aisi 304l stainless steel was carried out to fabricate the al/304l/al clad sheet composites. the maximum bond strength of 20 n/mm was acquired just by 38% reduction, for which the tearing of the aluminum sheet occurred during the peeling test. the microstructural evolution during subsequent postannealing heat treatment was systematically studied based on the impur...

Aluminum alloy sheets have several advantages such as the lightweight, high-specific strength and recycling efficiency. Therefore, aluminum alloy sheets in sheet forming have been used in various areas as automotive components and so forth. During the process of sheet forming, wrinkling which is caused by compression stress might occur and the formability of sheets was affected by occurrence of...

A flexible proximity sensor fully fabricated by inkjet printing is proposed in this paper. The flexible proximity sensor is composed of a ZnO layer sandwiched in between a flexible aluminum sheet and a web-shaped top electrode layer. The flexible aluminum sheet serves as the bottom electrode. The material of the top electrode layer is nano silver. Both the ZnO and top electrode layers are depos...

An Al/Stainless Steel/Al lamellar composite was produced by roll bonding of the starting sheets at 400 °C. Afterward, the roll bonded sheet was cut in half and the accumulative roll bonding (ARB) process at room temperature was applied seven times. As a result, the central steel layer fractured and distributed in the Al matrix among different layers introduced by the repetition of roll bonding ...

Metal coating, metal materials are of two or more layers. The coating metals are widely used in industry. These sheets or saving performance and cost effective solution or both the user. Performance coating metals according to usage in structural applications, settings thermal expansion of the thermo-mechanical control (thermostat), electrical, magnetic, corrosion resistant, flowering and decor...

A square sheet of aluminum foil is considered 2-dimensional because its mass is proportional to its diameter to the power of 2. A solid aluminum sphere is considered 3-dimensional because its mass is proportional to its diameter to the power of 3. An aluminum wire is considered 1dimensional because its mass is proportional to its length. The mass is proportional to length to the power of 1. Fro...

Aluminum alloy sheets have been widely used to build the thin-walled structures by mechanical clinching technology in recent years. However, there is an exterior protrusion located on the lower sheet and a pit on the upper sheet, which may restrict the application of the clinching technology in visible areas. In the present study, an improved clinched joint used to join aluminum alloy sheets wa...
