Tensile and fatigue properties of as-cast polycrystalline alumina-fiber-reinforced magnesium (ZE41A) composites were determined as a function of fiber orientation and fiber content. Fiber-dominant properties were studied on four fiber volume fractions of 35, 40, 45 and 55% at 24 C and 200 C testing temperatures. Off-axis, matrix-dominant properties were investigated at a constant fiber volume fraction (55%) at 24 C. An attempt was also made to identify the effects of the fiber/matrix interface, matrix chemistry and residual stresses on the resultant mechanical behavior of these composites.
