| Abstract: | he growth process of the reactive self-composing material (RSCM) and the influence of the process parameters on the structure and properties of the RSCM are described and discussed. Results have showed that the A12O3/Al ceramic matrix composite(CMC) can be obtained by oxidizing the aluminium alloy Al-3.0Mg-10Si at 1400-1600K. The content of the metal in it varies from 10% to 30% with the isothermal time.Few porous A12O3 / Al CMC containing 20% metal may be obtained, when the aluminium alloy is oxidized at 1573K for 10h, and it possesses the bend strength of 364MPa and the fracture toughness of 11 .0MPam1/2. |
