“…The grain size of the materials is 0.234 nm. The presence of elements such as magnesium, aluminium, silicon, and calcium make the compound overall non-ammable at the instance of combustion, as revealed by earlier workers [19,20]. Oxygen contributes to negligible weight loss when subjected to burning.…”

The emission of harmful elements from burning building ceiling materials and their attendant health effects on inhabitants within the vicinity of the emitted harmful elements is increasingly becoming a source of concern globally.Hence, the need to develop eco-friendly ame-retardant composite materials suitable for house ceiling purposes to forestall unwanted toxic emissions. This work identi ed the chemical structure of developed composite products and their emission performance during combustion. X-ray Diffraction (XRD) analysis was used for phase quanti cation and E550 combustion gas analyzer for emission characterization of the developed composites. Thermolyne 950 o C oven was employed for the combustion analysis of the prepared composite at 500 o C. Quasi negligible SO 2 level and CO 2 exist; however, A4, 0.3 Aldr 0.23 Cmt 0.3 Si 0.05 G 0.12 CS recorded maximum CO level, an indication of toxic a uence.The low mass losses of all of the composite materials, especially for A2, 0.6 Aldr 0.34 Cmt 0.05 G 0.01 OBSretard signi cantly due to its activities by the retardant constituent. The ame retardant nature of all produced composite was evidenced in their elemental composition, as there was an absence of ammable element and presence of stable insulating compound providing retardance to ame occurrences. These suppressions in the ame inclination of the reinforced materials were noticed within the boundaries of the ceiling crystals from the structural examination. The intermetallic phase from the diffraction intensities showed the presence of a signi cant second bond interstitial solidphase across the matrix, especially for 0.6 Aldr 0.34 Cmt 0.05 G 0.01 OBS ceiling material.

“…Nevertheless, AZ91 can also be used in the wrought form, where it achieves higher strength values (as fabricated as well as T6 state) than its contenders AZ31 and AZ61, stemming from the higher Al content [98]. Despite the rather high Al content present in the alloy, the binary phase Mg 17 Al 12 , typically found on the grain boundaries, can be completely dissolved by a solution heat treatment and therefore be utilized for precipitation hardening.…”

Interest in magnesium alloys and their applications has risen in recent years. This trend is mainly evident in casting applications, but wrought alloys are also increasingly coming into focus. Among the most common forming processes, forging is a promising candidate for the industrial production of magnesium wrought products. This review is intended to give a general introduction into the forging of magnesium alloys and to help in the practical realization of forged products. The basics of magnesium forging practice are described and possible problems as well as material properties are discussed. Several alloy systems containing aluminum, zinc or rare earth elements as well as biodegradable alloys are evaluated. Overall, the focus of the review is on the process control and processing parameters, from stock material to finished parts. A discussion of the mechanical properties is included. These data have been comprehensively reviewed and are listed for a variety of magnesium forging alloys.

“…The development in increasing thermal conductivity of magnesium alloys has supported battery-related applications [7]. On the other hand, flammability resistance has been a hot topic for magnesium alloys, and the related research has gained substantial progress which is highly valuable for aerospace applications [10][11][12][13][14][15][16][17][18][19]. Attributed to the above advantages, magnesium alloys have become one of the lightest and most popular structural metals utilized extensively in the automotive industry.…”

High-pressure die-cast (HPDC) magnesium alloys have seen diverse applications in the automotive industry, primarily driven by requirements in internal combustion engine (ICE) vehicles. As the automotive industry is transitioning to an electric vehicle (EV) architecture, there is a great potential for novel applications to improve driving range efficiency. In addition, there is a trend toward larger-sized automotive die castings and an increased interest in aerospace applications due to weight reduction. In this chapter, we reviewed the traditional automotive structural applications in ICE vehicles, as well as current and potential future EV and aerospace applications of HPDC magnesium alloys. The structural applications using AM50, AM60, AZ91 and AE44 magnesium alloys in traditional vehicles can be applied to modern EVs. Additionally, magnesium alloys with varying degrees of higher thermal conductivity, improved castability, superior high temperature properties and flammability need to be developed to replace battery and aerospace in-cabin-related structural materials to meet all safety requirements. Several newly developed magnesium alloys with superior castability are also reviewed for potential automotive and aerospace applications.
