“…If anything has to be learnt from the past than the fact that no failure or accident was reported in any literature in public domain where any of the magnesium based materials was the key factor causing a failure [21]. While there is a rich history of use of magnesium based materials in aerospace sector as can be seen from Table 4, its full potential is not realized [22][23][24][25][26][27][28][29][30][31][32][33][34][35][36][37][38][39] Table 2 shows the types of materials used in a typical commercial aircraft. Maximum service temperature of some of polymer based composites is shown in Table 5 [40,41].…”

“…As indicated earlier, corrosion is one of the main issue that is faced by magnesium and its alloys while in service in the past [21,29,30,[44][45][46][47]. It is also important from a maintenance perspective and hence the use of corrosion resistant alloys and corrosion management system for magnesium based materials is of paramount importance.…”

This article highlights the importance of light weighting option in aerospace sector as an effective measure of reducing the carbon dioxide emission. Various methods of reduction in fuel consumption in aerospace sector are highlighted. Use of magnesium based materials as replacement for aluminum based materials and fiber based composites for light weighting is highlighted with an example. Myths of ignitability and flammability are dispelled by directing the attention of the readers to the inherent thermal properties of magnesium in bulk form and through highlighting the past and present use of magnesium based materials in both fighter and commercial aircrafts. Information is also provided on the availability of some coating techniques that can bring the corrosion resistance of magnesium based materials at par with aluminum based materials.

“…AZ92/91/81 sand and permanent mold castings were used on this airplane [11]. No parts were rejected for fire, but corrosion was the main issue [11,12]. Accordingly, International Air Transport Association (IATA) enacted legislation limiting the use of magnesium-based materi- Boeing CH 47 Chinook, a heavy lift helicopter ( Figure 15.)…”

As-cast Mg-4Zn-0.5Zr, Mg-4Zn-2Gd-0.5Zr and Mg-4Zn-2Nd-0.5Zr alloys were investigated by in situ synchrotron radiation diffraction during hot compression at 350 °C using the facilities of P07 beamline of Petra III at Deutsches Elektronen Synchrotron (DESY), Hamburg, Germany. The specimens were heated at a rate of 100 K/min and compressed with an initial strain rate of 1.1 x 10 -3 s -1 up to 30 % strain. The addition of rare earth elements improved the yield strength from 23 MPa in the Mg-4Zn-0.5Zr alloy up to 40 MPa in the alloy with Nd and Gd. Continuous dynamic recrystallization played an important role in the Mg-4Zn-0.5Zr alloy during deformation and twinning was not dominant. Discontinuous dynamic recrystallization was observed in the in the Mg-4Zn-2Gd-0.5Zr along the grain boundary regions while the grains remained largely without any recrystallization. In the Mg-4Zn-2Gd-0.5Zr and Mg-4Zn-2Nd-0.5Zr alloys the contribution of twinning to deformation was observed at 350 °C. Reasons for these differences will be discussed with respect to microstructures of the alloys.
