Abstract
The use of a structural material is dictated by a number of factors including mechanical and physical properties and cost (which relates in part to availability).
The latter factor plays a major role in use levels (Fig. 8.107), and in the industries in which they are used i.e. (Fig. 8.108 and Table 8.10). Magnesium is the lightest of all commonly used metals and is thus very attractive for transportation applications Figs. 8.109 and 8.110 [50–63]. It also has other desirable features including reasonable ductility, better damping characteristics than aluminum and excellent castability. Magnesium can be joined by riveting or any commonly used welding methods. Magnesium can be machined
faster and has the best strength-to-density ratio of any of the commonly used
structural metals. All of these characteristics make magnesium attractive to the
aerospace industry. However, magnesium exhibits a number of negative features
including inferior strength/ductility, fracture toughness, fatigue and creep compared to aluminum and a generally less than desirable corrosion behavior and galvanic corrosion resistance, which has been described as “awful.” Magnesium also suffers from the perception that it readily burns – a legacy from a demonstration by a high school science teacher.
