Available in PDF, EPUB and Kindle. Book excerpt: The objective of this program was to develop methods for improving the strengths of joints in high-strength aluminum alloys. Details of the work during the period May 1, 1949, to October 31, 1949, are also presented. The all-weld-metal strength properties and the aging characteristics were determined for welds made between copper dams and in alloy base plates with aluminum-magnesium alloys containing from 5 to 15 per cent magnesium. Transverse tensile tests of joints made in 61S-T6, 24S-T4, and 75S-T6 plates with these alloys were also carried out. Some cold-welding tests were made. The major effort during the third contract period was devoted to testing two series of aluminum-alloy filler metals. One of these series was based on the Frontier 40E composition (5.5% Zn, 0.5% Mg, 0.2% Ti, 0.5% Cr), the other was a series of aluminum-magnesium alloys covering the range from 5 to 15 per cent magnesium.

Available in PDF, EPUB and Kindle. Book excerpt: The application of aluminium-lithium alloys over a wide range of engineering technologies will require development of both effective methods for joining these materials and through understanding of their welding metallurgy. This chapter covers the pertinent literature regarding the weld metal porosity, susceptibility to cracking during welding, eqiaxed zone formation and associated fusion boundary cracking, mechanical properties and corrosion behaviour of welds. Microstructural modification is especially attractive for alloys with pronounced hot cracking susceptibility. Aluminum–lithium alloys are one such class of materials. Since the hot cracking tendency is known to be a function of weld metal composition, several crack resistant filler materials such as AA 2319, AA 4043 and AA 5356 are in common use. While primary approach to the problem is thus to modify weld metal chemistry, a secondary solution is to reduce the coarseness of the solidification structure. Of the various techniques available for modifying the structure, pulsed current, magnetic arc oscillation techniques of gas tungsten arc welding and inoculation using grain refining additions offers the greatest promise for practical applications. Improving weldability of these alloys through modification of fusion zone microstructure are covered in this chapter. Lastly, solid state welding processes such as friction and friction stir welding of Al-Li alloys are briefly discussed.

This book was released on 2011-02 with total page 324 pages. Available in PDF, EPUB and Kindle. Book excerpt: Friction Stir Welding (FSW) is known to result in a complex microstructural development, with features that remain unexplained, such as: the formation of the onion rings structure. Moreover, various microstructural factors have been suggested to control the strength in Al-Mg AA5xxx welds, without identifying their relative contribution. Furthermore, the influence of the basemetal microstructural parameters (e.g. grains, intermetallic particles, stored energy) on the microstructure-property development has not been previously investigated. These issues are addressed in the present study.

This book was released on 2011 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The ternary Al-Cu-Mg system 2xxx series aluminium alloys were examined as constructionmaterials for armour system applications based upon comparable ballistic properties to thecurrently employed Al-7xxx series alloys. Utilising MIG welding solidification cracking wasevident when welding constrained Al-2024 candidate base material using Al-2319 filler, theonly available consumable wire for this series. A previously developed thermodynamicmodel suggested that an incompatible weld chemistry resulted when welding with this fillerwhich would result in hot cracking due to a wide weld pool freezing range and a low volumefraction of eutectic liquid. As this filler wire was the only commercially available Al-2xxxfiller this was seen as the principal limiting factor for exploiting this alloy series. The solutionwas to vary and control weld chemistry. Two approaches were taken. Firstly advanced arcwelding was used to control weld dilution with the base material. A clad layer exhibiting aless crack susceptible composition was deposited using the Cold Metal Transfer process andthe binary Al-2319 filler wire. Onto this layer the same filler could then be deposited toprovide a structural joint. Although not fully validated, by limiting weld dilution with thebase material this technique showed potential as an alternative method for suppressingsolidification cracking. The second approach, which forms the core of this work, adapted theconventional tandem MIG welding process to mix different series consumable fillers in asingle weld pool to control weld composition. A range of ternary weld mixtures wereproduced which resulted in the development of a robust thermodynamic model. Validationusing this system resulted in weld cracking being eradicated. The concept was then furtherdeveloped to weld using three filler wires; this expanded the mixing range and allowedfurther model validation. A range of crack free compositions were produced with differingmechanical properties. An optimum weld composition was determined that was then used forcharacterisation of the weldment. By varying heat input, base material HAZ softening wascontrolled with joint failure confined to the weld / base material interface. This was attributedto grain boundary liquation due to the welding temperatures involved resulting in solute richgrain boundaries. These areas did not deform easily under tensile loading initiating fracture ofthe joint. Acceptable joint strengths were realised however ductility was reduced due to theidentified failure mode. Although not tested to military specifications, acceptable mechanicaltest values were recorded which were closely compliant with the minimum requirements forarmour system specifications. As a consequence a filler wire composition was recommendedfor future prototype development.

Available in PDF, EPUB and Kindle. Book excerpt: Because lithium is the least dense elemental metal, materials scientists and engineers have been working for decades to develop a commercially viable aluminum-lithium (Al-Li) alloy that would be even lighter and stiffer than other aluminum alloys. The first two generations of Al-Li alloys tended to suffer from several problems, including poor ductility and fracture toughness; unreliable properties, fatigue and fracture resistance; and unreliable corrosion resistance. Now, new third generation Al-Li alloys with significantly reduced lithium content and other improvements are promising a revival for Al-Li applications in modern aircraft and aerospace vehicles. Over the last few years, these newer Al-Li alloys have attracted increasing global interest for widespread applications in the aerospace industry largely because of soaring fuel costs and the development of a new generation of civil and military aircraft. This contributed book, featuring many of the top researchers in the field, is the first up-to-date international reference for Al-Li material research, alloy development, structural design and aerospace systems engineering. Provides a complete treatment of the new generation of low-density AL-Li alloys, including microstructure, mechanical behavoir, processing and applications Covers the history of earlier generation AL-Li alloys, their basic problems, why they were never widely used, and why the new third generation Al-Li alloys could eventually replace not only traditional aluminum alloys but more expensive composite materials Contains two full chapters devoted to applications in the aircraft and aerospace fields, where the lighter, stronger Al-Li alloys mean better performing, more fuel-efficient aircraft

This book was released on 1967 with total page 97 pages. Available in PDF, EPUB and Kindle. Book excerpt: The objective of the program is to develop a stress corrosion resistant high strength aluminum alloy through addition of minor elements and variations in heat treatment. In Phase I, fifteen special chemistry alloys based on the 7075 composition were prepared in plate form with additions of silver, boron, cerium, yttrium and zirconium. The materials evaluation consisted of metallographic and aging studies, stress corrosion testing and determination of mechanical and fracture properties. The silver bearing alloys, while not immune, were the only alloys to show increased resistance to stress corrosion cracking in the T6 temper. Overaging treatments improved the stress corrosion resistance of all alloy combinations tested. Mechanical property evaluations and transmission electron microscopy studies indicate that silver additions retard the rate of overaging and promote a finer dispersion of M' precipitate, which allow these materials to attain stress corrosion resistance without large decreases in tensile strength. However, the increased quench sensitivity of silver-bearing alloys may limit this strength advantage to thinner sections unless other changes are made in chemical composition. On the basis of stress corrosion, fatigue, fracture toughness, and strength requirements, five step-aged special chemistry alloys are proposed for Phase II testing. (Author).
