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 percent at 24 C and 200 C testing temperatures. Off-axis, matrix dominant properties were investigated at a constant fiber volume fraction 55 percent at 24 C. An attempt was also made to identify the effects of the fibermatrix interface, matrix chemistry and residual stresses on the resultant mechanical behavior of these composites.
