Production and Fabrication Technology Development of Aluminum Useful for Automobile Lightweighting

Abstract

To undertake the development of technology to increase consumption of aluminum in passenger cars for improved fuel economy through lightweighting of cars as a measure to control global warming. More specifically, R&D is conducted on the following R&D themes to develop a material with a high formability and a technology to join a steel material, as well as to establish a technology to create materials with a good shock absorption performance.

Microstructure modification and related mechanism of spray‐formed Fe‐bearing hypereutectic Al‐Si alloys

“…But the present study shows that a-Al 15 (Fe,Cr) 3 Si 2 phase in SF-C2 alloy are still smaller than 3-5 lm (Fig. 4(a)) after being heat-treated at 803 K for 20 h. By extending time to 50 h, the growth or coarsening of granular a-Al 15 (Fe,Cr) 3 Si 2 phase was not observed (Fig.…”

“…1(a)) cannot be entirely replaced by granular a-Al 15 (Fe,Cr) 3 Si 2 phase when the TM/Fe = 0.4 (only with 2 wt.% Cr addition). Increasing TM/Fe ratio to 0.6 (with (2Cr+1Mn) addition) promotes the formation of almost single granular a-Al 15 (Fe,TM) 3 Si 2 phase for the sufficient Cr/Mn elements.…”

Fabrication, Processing, Properties, and Applications of Closed-Cell Aluminum Foams: A Review

“…Because of these excellent properties, aluminum foams have been used in many places such as sound absorption barriers, architectural decoration, military protection, aerospace, and aeronautics parts. An excellent combination of mechanical and functional properties provides wide prospects for the application of aluminum foams [3,10,31,32]. ,c) open-cell aluminum foam [34,35] (reproduced with permission from Elsevier and Hindawi).…”

Study on Flow Stress Model of AA5005 Material

“…We can apply advanced manufacturing technology, optimize automobile frame structure, and use a lot of lightweight materials in remanufacturing to achieve automobile lightweight [2] . Compared with other steel materials, aluminum alloy, as a light material with good formability, corrosion resistance, small specific gravity and relatively rich resources, is more and more widely used in automobiles.…”
