Available in PDF, EPUB and Kindle. Book excerpt: Part I discusses the development of an aluminum-magnesium-silicon alloy that may combine strength, extrudability, favorable corrosion resistance with low cost and scrap compatibility. The first part of the study determined the effects of small composition, heat treatment and mechanical processing changes on the ambient temperature tensile properties of the alloy. A combination of magnesium and silicon of about 2%, 1% copper, 0.2% chromium and 0.1% vanadium can produce a T6 alloy with significant higher strength, fatigue and corrosion fatigue properties for both ingot and extrusion than those of 6061 but with only a modest increase in cost. The new alloy has been designated as AA6069. The second part of the study determined the T6 properties of 6069 alloy. The tensile test results of cold and hot extrusions of hollow, solid bars, and high pressure cylinders indicate that the T6 properties ranged from 55-70 ksi (380-490 MPa) UTS, 50-65 ksi (345-450 MPa) yield strength, and 10-18% elongation. It also appears that the fracture toughness and general corrosion resistance in saline environment are comparable or better than those of 6061 T6. Part II attempted to evaluate the formation, formability, thermal and mechanical properties of semi-solid A356, A357 and modified aluminum silicon semi-solid alloys. The semi-solid alloy microstructure was produced in this study by purely thermal treatment rather than conventional and expensive electromagnetic or mechanical stirring. Three heat-up stages in semi-solid treatment were evaluated. Stage I is related to the heating of the alloy in the solid state. Stage II is related to the eutectic reaction. Stage III is related to the heating of the semi-solid slurry. Stage II requires the longest time of the three heat-up stages due to the endothermic reaction on heating. An increase of furnace temperature can greatly reduce the time of stage II. The atmosphere (vacuum, air, argon) of the semi-solid treatment does not appear to greatly affect the T6 properties of semi-solid alloys. The microstructure and T6 properties of semi-solid A356 do not appear sensitive to the homogenization treatments before semi-solid treatment. The porosity of semi-solid ingots and pressed parts increases as the cooling rate decreases in unformed and subsequent-to-moderate pressure forming. The T6 properties basically appear sensitive to voids, with a degradation of properties as the void concentration increases. The formability of A357 may be improved as the spheroidal particle size decreases. Hence, formability may improve with decreasing ingot grain size. The mechanism of coarsening of the solid phase at isothermal temperatures is related to Ostwald ripening and/or "merging" of particles. The mechanical properties of die-casting parts show that the method of thermal treatment to produce a spheroidal microstructure is an effective method for industrial production of semi-solid aluminum-silicon alloys.

Download or read book Aluminum Structures written by J. Randolph Kissell and published by Wiley-Interscience. This book was released on 1995 with total page 442 pages. Available in PDF, EPUB and Kindle. Book excerpt: Despite its unique and enormous advantages, most engineers fail to consider using aluminum, even in structural situations where its strength, light weight, and corrosion resistance should make it the metal of choice. Aluminum Structures: A Guide to Their Specifications and Design offers engineers, designers, and architects a comprehensive guide to designing aluminum structures and, consequently, a rare opportunity to expand their design capabilities quickly. This book's broad coverage includes the properties of aluminum, its structural performance in beams, columns and members, aluminum fabrication, welding and mechanical connections, and its inspection and testing. Special attention is paid to those features of aluminum that differentiate it from other structural materials, most particularly steel. Because the aim of this book is to apply aluminum design methods to real-world problems, it emphasizes total structures as examples and illustrates the use of ASD vs. LRFD methods. Thoroughly up-to-date, this book describes advanced design techniques that have been used in successful aluminum structures, including a step-by-step design process for each of several structural systems. To help professionals design with aluminum easily and confidently, this book is keyed to the latest edition of the Aluminum Association's Specifications for Aluminum Structures. Numerous design aids—tables, charts, and graphs—eliminate the need for lengthy, repetitive calculations. Engineers, designers, architects, and fabricators will find this book not only a comprehensive guide to the practice of designing aluminum structures, but a source of inspiration for designing in a whole new medium. A state-of-the-art guide to the exciting new realm of aluminum structures Aluminum Structures: A Guide to Their Specifications and Design This comprehensive guide has a dual purpose: to explain the practice of designing aluminum structures, and to invite design, engineering, and architecture professionals to expand their capabilities through the use of aluminum as a structural material. Aluminum Structures: A Guide to Their Specifications and Design demonstrates, through detailed examples of total structures, how this strong, lightweight, corrosion-resistant material opens up whole new design possibilities. Topics covered include the properties of aluminum, its structural performance, aluminum fabrication, welding and mechanical connections, and inspection and testing. Support materials, in the form of tables, charts, and graphs, make using the text easy and efficient.
