Abstract

Multiphase nanocomposite gradient structure (for phase composition, hardness) at the pulse photon processing with gas-discharge lamp radiation treatment (IFO) is obtained in aluminum amorphous alloys (Al=85 at. %) alloyed with transition (Ni=5÷7 at. %, Fe=4÷7 at. %) and rare-earth (La=3÷4 at. %) elements. IFO critical parameters when crystallization at subsurface layers of amorphous ribbons at the radiation treatment side starts are defined (fluence F=10 J/cm2; duration τ~0,5 sec). It is shown that alloy composition alteration within the bounds of the indicated alloying elements content does not have significant influence on IFO critical parameters. Through-thickness crystallization of the amorphous ribbons (25-micron thickness) was observed after IFO with F≥20 J/cm2. Hardness of alloys after IFO with different parameters is determined. Alloys’ phase composition was analyzed after the IFO with various parameters.
