welding of aluminum alloys. Loss of volatile alloying elements, such as magnesium and zinc, due to se-lective vaporization is a common occur-rence in the laser welding of aluminum alloys (Refs. 18–22). Automotive alu-minum alloys are either solid-solution
Friction stir welding of dissimilar alloys – a perspective T. DebRoy*1 and H. K. D. H. Bhadeshia2 Friction stir welding does not involve bulk melting of the components that are joined. This has inspired attempts to exploit it for joining materials which differ in properties, chemical composition or structure, and where fusion can lead to detrimental reactions.
Extrusion welding takes place during the manufacturing of hollow profiles made of lightweight alloys, such as aluminum and magnesium. For many industrial appliions, a porthole die or a die with a mandrel is used. In hot extrusion with a porthole die, the billet
19/9/2013· Magnesium alloys containing more than 1.5% Al are susceptible to stress corrosion and must be stress relieved after welding. Iron, copper and nickel are considered impurities to be limited because they degrade the corrosion resistance of magnesium alloys.
Chromium is a common addition to many alloys of the aluminum-magnesium, aluminum-magnesium-silicon, and aluminum-magnesium-zinc groups, in which it is added in amounts generally not exceeding 0.35%. In excess of these limits, it tends to form very coarse constituents with other impurities or additions such as manganese, iron, and titanium.
aimed to produce bulk metallic glasses materials by welding the ribbon packages in ultrasonic field. In order to prove the preservation of the amorphous structure of both the primary welding alloys as well as after the welding of the amorphous ribbons
The 5XX aluminum/magnesium alloys are similar to wrought 5XXX alloys like 5083. There are no 6XX alloys. The situation is the same with the 2XX and 7XX casting alloys. In general, avoid welding them. Fortunately, both the 3XX and 5XX casting alloys are and
Magnesium ions are essential to the basic nucleic acid chemistry of life, and thus are essential to all cells of all known living organisms. Plants have an additional use for magnesium in that chlorophylls are magnesium-centered porphyrins.Many enzymes require the presence of magnesium ions for their alytic action, especially enzymes utilizing ATP, or those which use other nucleotides to
With a bulk density of in average1.74 g/cm³, Magnesium is a lot lighter than steel (< 70%) or even Aluminium (< 30%). Due to its high specific stability and the mentioned density it is the most favoured raw material in automotive, aviation and aerospace.
The CO2 laser welding process is shown to increase the microhardness of both magnesium alloys. Furthermore, grain refinement is responsible for the maximum hardness in the FZ of both weldments. The AZ61 weldment has a higher content of Al, resulting in a greater grain refinement.

Surface Engineering of Light Alloys: Aluminium, Magnesium and Titanium Alloys H. Dong The growing use of light alloys in industries such as aerospace, sports equipment and biomedical devices is driving research into surface engineering technologies to enhance their properties for the desired end use.
High strength-density ratios have made the 7XXX aluminum alloys extremely attractive for use in aircraft structures. Despite this superior property, limited corrosion, fatigue, and fracture resistance has restricted their commercial usage in maximum-strength tempers.
The advancement in the appliion of light alloys such as magnesium and titanium is closely related to the state of the art of joining them. As a new type of solid-phase welding, ultrasonic spot welding is an effective way to achieve joints of high strength. In this
Magnesium and magnesium alloys are nonferrous metals with low density, good ductility, moderate strength, and good corrosion resistance. Pure Magnesium - Magnesium is a silvery-white, light-weight metal that is relatively strong and tarnishes some through air contact.
The CO 2 laser welding process is shown to increase the microhardness of both magnesium alloys. Furthermore, grain refinement is responsible for the maximum hardness in the FZ of both weldments. The AZ61 weldment has a higher content of Al, resulting in a greater grain refinement.
Welding of magnesium alloys to aluminium alloys is of particular interest since such a coination is likely to be required in any future magnesium intensive multi-material vehicle. The difficulty in this case is to control the rapid reaction at the weld interface that occurs between the aluminium and magnesium.

The main difficulty when joining magnesium (Mg) and aluminum (Al) alloys by fusion welding process lies in the existence of oxide films and formation of brittle intermetallic in the weld region. However, solid-state welding processes such as friction welding and diffusion bonding are suitable processes to join these two materials.
