Magnesium alloys, having some excellent properties such as low density, high
specific strength and stiffness and so on, have received more concerns as very
attractive materials for structural components required weight reduction, energy
saving and reduction of the environmental loads to the globe. With development
of extruding and rolling technology in present-day, wrought magnesium alloys are
expected to use of mechanical components under high oscillating load, instead of
using cast magnesium alloys which have disadvantages in defects such as casting
porosity, cavity and microscopic shrink hole. For application of the wrought
alloys to load-bearing components, it is important to evaluate fatigue properties. It
is already recognized for magnesium alloys to result a strong crystallographic
anisotropy and texture because of the limited number of active slip systems and
then operations of twinning systems in hexagonal close packed lattice structure
