| Abstract: | The research of Al2O3 particles reinforced aluminum matrix composites fabricated byLanxide process is discribed here. The microstructures were analysed and the tensile properties, instantaneous heat resistance, thermal conduction were tested. The results show that the microstructures are dense. In the interface of (Al2O3),/Al, MgAl2O4 spinels are in-situ formed. The ultimatetensile strength is 350~378 MPa and the tensile modulus is 103~121. 6 GPa. Failure strain is1. 96%. The composites are non-abration within 20s while heated by O2-C2H2 flame of 1080C. Thethermal conductivity at room temperature is 30. 38W. (m-1. K-1) |
