1.1 This specification is used to indicate the resistance to distortion of bare and two-side Alclad, flat sheet aluminum that will be chemically milled (often in the manufacture of aircraft skin panels). 1.2 This specification is intended for bare and two-side Alclad aluminum alloy in the T temper, which is the form of flat sheet having a thickness between 0.032 to 0.249 in. (0.8 to 6.3 mm). 1.3 Product having the capability prescribed by this specification is available in limited quantities and tempers because of the special processing required.

Abstract High power gasoline engines require improved heat transfer between the cylinder block and water jacket because the heat load is increased when GDI, turbo charger, etc. are used. The use of a hypereutectic aluminum alloy cylinder liner has the advantage of thermal conductivity. In addition, the aluminum liner has the effect of low bore distortion and weight reduction compared with the gray cast iron liner. Use of an aluminum liner is a good solution for high power gasoline engines.

Abstract Heat treated cast aluminum components like engine blocks and cylinder heads can develop significant amount of residual stress and distortion particularly with water quench. To incorporate the influence of residual stress and distortion in cast aluminum product design, a rapid simulation approach has been developed based on artificial neural network and component geometry characteristics. Multilayer feed-forward artificial neural network (ANN) models were trained and verified using FEA residual stress and distortion predictions together with part geometry information such as curvature, maximum dihedral angle, topologic features including node's neighbors, as well as quench parameters like quench temperature and quench media.

Abstract The effect of cold-working, i.e. wire drawing, on the corrosion behavior of a 6101 and a 1370 aluminum alloy was investigated in NaCl solutions. For the both alloys, a “grain size - corrosion resistance” was highlighted. The preliminary works performed on Al-Cu welds showed two scales of heterogeneity and two scales of heterogeneity of media which are not considered by the current automotive specifications. Consequently, it seems to be necessary to establish new pertinent specifications to evaluate the new Al solutions.

A comparison of welding techniques was performed to determine the most effective method for producing aluminum tailor-welded blanks for high volume automotive applications. Aluminum sheet was joined with an emphasis on post weld formability, surface quality and weld speed. Comparative results from several laser based welding techniques along with friction stir welding are presented. The results of this study demonstrate a quantitative comparison of weld methodologies in preparing tailor-welded aluminum stampings for high volume production in the automotive industry. Evaluation of nearly a dozen welding variations ultimately led to down selecting a single process based on post-weld quality and performance.

Advanced lightweight materials are increasingly being incorporated into new vehicle designs by automakers to enhance performance and assist in complying with increasing requirements of corporate average fuel economy standards. To assess the primary energy and carbon dioxide equivalent (CO2e) implications of vehicle designs utilizing these materials, this study examines the potential life cycle impacts of two lightweight material alternative vehicle designs, i.e., steel and aluminum of a typical passenger vehicle operated today in North America. LCA for three common alternative lightweight vehicle designs are evaluated: current production (“Baseline”), an advanced high strength steel and aluminum design (“LWSV”), and an aluminum-intensive design (AIV). This study focuses on body-in-white and closures since these are the largest automotive systems by weight accounting for approximately 40% of total curb weight of a typical passenger vehicle. Secondary mass savings resulting from body lightweighting are considered for the vehicles' engine, driveline and suspension.

Preventing future problems and troubleshooting existing problems in today's stamping plants requires greater stamping process knowledge. The link between inputs and outputs isn't as clear as many think, increasing the need for detailed understanding of the variables involved. This course discusses the key inputs and outputs associated with sheet metal stamping, including important elements for controlling the process and making it more robust. The course reviews sheet metal characteristics and their application, especially from a formability standpoint, using many automotive-related examples. Common issues such as springback, dent resistance, and process differences among mild steel, high strength steel, bake hardenable steel, and aluminum are discussed. Stamping die types and functions, in particular the types of dies used in draw forming, are explained. Mechanical presses and lubrication are briefly discussed as other variables in the process. Other processes, including tube and sheet hydroforming, and progressive dies are covered in less detail.
