ABSTRACT
X-ray diffraction analysis, optical and electron microscopy made a comparative study of the structure of the Al90Y10 alloy, nanotechnology and cooling technology, depending on the temperature and cooling rate of the melt. It is shown that under all considered crystallization conditions in the Al90Y10 alloy only crystalline phases are formed: α-Al and Al3Y. The influence of temperature, cooling rate and pressure on the morphology, size and microhardness of the structural constituents of the alloy-primary yttrium aluminide and eutectic crystals was established.
