Recently, a number of magnesium alloys have been used as structural components, such as cases for portable electronic equipment due to their high specific strength and good thermal conductivity. To reduce the weight of automobiles to reduce energy consumption, magnesium alloys are also expected to be used in structural components. In order for magnesium to be used in structural components, it is necessary that it exhibits sufficient strength and ductility under dynamic loading as well as static loading at ambient temperature. Elongation-to-failure at a dynamic strain rate compared to a static strain rate for some structural metals
are shown in Figure 10.1. Elongation-to-failure of magnesium at a dynamic strain rate is lower than that at a static strain rate
as well as other hexagonal close parted metals, such as zinc.
