and corrosion resistance have led to greater interest in magnesium alloys for aerospace and speciality applications, and alloys are now being specified on programmes such as the McDonnell Unclassified Heidi Maupin1, Eric Nyberg2 and Suveen N.

Douglas MD 500 helicopter. For many years, RZ5 alloy has been the preferred material for helicopter transmission casings due to the combination of low Recently, magnesium alloys experience renaissance period in their application in automotive industries. The comparison of WE43C with ASTM 7475 was performed. Magnesium, with a density of only 65% of that of aluminium, could be a breakthrough technology in the aerospace industry if used for cost-efficient, low-weight components and airframe structures. the metal is predominantly used in die-cast parts including four-wheel-drive transfer cases, transmission cases, engine cradles, steering-wheel components, Magnesium alloys can be categorized into two groups: cast alloys and wrought alloys. New high-strength alloys, advanced surface treatment technologies and a correct understanding of 'magnesium flammability' form the basis for magnesium comeback in aerospace industry. Due to the high operating temperature of racing engines, WE54 castings have been used for a variety of Formula 1 engine parts and are used for engine components for a The WE43C alloy is a magnesium alloy, Mg is the lightest and most abundant metal present on the earth's surface is an alternative to commercial aluminum alloys. In motor racing, RZ5 is generally used for gearbox casings although MSR/EQ21 alloys are also being used increasingly due to arduous racing conditions. For conventional passenger vehicles nearly 90% of their total life time energy consumption used from the time of production to the time of disuse or scraping is consumed by carrying their own Magnesium alloy forgings are also used in aerospace applications including critical gearbox parts for the Westland Sea King helicopter and aircraft wheels, both in ZW3. Cast alloysare basically made by pouring the molten liquid metal into a mould, within which it solidifies into the required shape. Magnesium alloys have its corrosion and high temperature properties. tural applications of magnesium castings in automotive, aerospace and power tools industries are reviewed in this paper. always been attractive to designers due to their low density, only two thirds that of aluminium. density and good mechanical properties. 10-15% of magnesium components in civil aircraft in 2015-2020 look like a real target. For this application, Magnesium is currently being used in gearboxes, steering columns and driver’s air bag housings as well as in steering wheels, seat frames and fuel tank covers. There are still other fields of application in which magnesium use is on the rise. As the material properties of magnesium alloys … The rationale behind this development is to improve fuel economy, therefore to lower the toxic emissions and consequently to cut on the air pollution. A further requirement in recent years has been for superior corrosion performance and dramatic improvements have been demonstrated for new magnesium alloys. Forged magnesium parts are also used in aero engine applications. used in aeronautic industry, Development of material models and failure criteria, Manufacturing and testing of structural elements, Preparation of the qualification of Mg for aerospace applications, Several product forms and alloys are available; ρ=1.7-1.9 g/cm3, Advanced alloys with good mechanical/technological properties, More than 33 % increase in specific strength possible, Fatigue strength (Kt=1.0, R=0.1) in rage of 150 - 220 MPa, Flammability tests and test definition has been initiated by AEROMAG, Partners with FAA; Full scale test is under progress at FAA, Intrinsic corrosion behavior of alloys has improved; RE based alloys, Show in general better corrosion behavior than AlZn systems, Green surface protection systems are evaluated, dep. Magnesium Alloys in Army Applications: Past, Current and Future Solutions The findings in this report are not to be construed as an official Department of the Defense, U.S. Army or Department of Energy position unless so designated by other authorized documents. Finally, material-adapted design and the evaluation of structural behaviour were investigated to close the process and development chain for aeronautic components.
