Tensile and Fatigue Behavior of Alumina Fiber Reinforced Magnesium Composites

Abstract

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 fiber/matrix interface, matrix chemistry and residual stresses on the resultant mechanical behavior of these composites. Keywords: Metal matrix composites; Fracture (Mechanics).
