The room temperature mechanical properties and high temperature creep behavior of AZ91 alloy reinforced with SiC p synthesized via stir casting have been evaluated. The mechanical properties showed improvement with respect to the amount of reinforcement content. The creep testing of the composites carried out at a temperature of 175 C under constant stress of 80, 100 and 120 MPa reveals different creep characteristics depending upon the reinforcement content and the applied load. The true
