Tensile strength and fracture toughness of two magnesium metal matrix composites

Abstract

Metal matrix composites of two magnesium alloys (AM100 and ZC63) with saffil alumina fibre reinforcements were produced using a squeeze infiltration technique. Mechanical properties were assessed, followed by analysis of the fractured specimens. From the strength, toughness and the fractographic analysis, attempts were made to elucidate the influence of the matrix, fibre volume fraction and the fibre/matrix interface on the properties.
