摘    要:
The process of the directed oxidiation of al-loy Al-1%Mg-7%Si was invertigated by X-Ray diffraction(XRD),optical microscopy,scanning electron microscopy(SEM)and energy dispersive spectrometer(EDS),which in-cluded evolution of the surface of the melt in the incubationperiod,nucleation of Al_2O_3/metal composite and microstruc-ture of Lanxide material its growth front.Some new resultsabout the mechanism of the for mation of Al_2O_3 are involved.

Abstract:
The process of the directed oxidiation of alloy Al-1%Mg-7%Si was invertigated by X-Ray diffraction (XRD). optical microscopy, scanning electron microscopy (SEM) and energy dispersive spectrometer(EDS) ,which included evolution of the surface of the melt in the incubation period, nucleation of Al2O3/metal composite and microstruc-ture of Lanxide material its growth front . Some new results about the mechanism of the for mation of Al2O3 are involved.
Keywords:A12O3/Al  composites  Lanxide meteri-al  growth mechanism
