Influence of Temperature on Fracture Mechanisms of Magnesium Composites

Abstract:

Article Preview

Magnesium alloy AZ91 (9 % Al, 1 % Zn, 0.2 % Mn in wt.%) with different reinforcements has been used to study fracture mechanisms and crack development. SiC particles and /or Saffil fibres were used as the reinforcement. Fracture surfaces of specimens prepared by impact tests in the temperature range from room temperature to 300 °C were investigated by scanning electron microscope (SEM). Possible mechanisms of fracture are discussed in the relation to the test temperature.
