    В этой книге демонстрируется использование метода порошковой металлургии для получения объемных нанокомпозитов с алюминиевой матрицей и электронно-лучевой обработки поверхности нанокомпозитов с наполнителями из наночастиц. В нем разъясняются микроструктура и свойства поверхностных и объемных нанокомпозитов на алюминиевой основе, а также исследуется роль наночастиц в процессе формирования микроструктуры и упрочнения нанокомпозитов. В книге также моделируется процесс формирования структуры в сплаве AlSi12Cu2NiMg, подвергнутом электронно-лучевой обработке, с использованием программного обеспечения MAGMASOFT®.Используемые программы Adobe AcrobatThis book demonstrates the use of the powder metallurgy method for producing bulk aluminum matrix nanocomposites and electron beam treatment for the surface nanocomposites with nanoparticle fillers. It clarifies the microstructure and properties of the surface and bulk nanocomposites on the aluminum base, and explores the role of nanoparticles in the process of microstructure formation and strengthening of nanocomposites. The book also simulates the structure formation process in AlSi12Cu2NiMg alloy, subjected to electron beam treatment, using the MAGMASOFT® software

    Preparation of soft magnetic alloys Fe100-x-ySixPy (0 < X < 9,0 < y < 0.6 wt%), using solid phase diffusion-sintering method

    A solid phase sintering diffusion (SPSD) method was used at the production of the soft magnetic alloys Fe100-x-ySixPy (0<x<9, 0<y<0.6 in wt%) from Fe-based powders. The method allows in situ formation of the desired composition of the final product during the sintering process and eliminates the production difficulties due to the brittleness of the alloying powders. A mathematical model of the diffusion processes at SPSD is proposed, which allows estimation of the processing time required for homogenisation of the alloying elements. The magnetic properties of the materials Fe100-x-ySixPy (0<x<9, 0<y<0.6 wt%) obtained by means of the SPSD method have been studied. It was found that alloying with Si and P leads to considerable increase of the initial and maximal magnetic permeability and reduction of the total power losses. (C) 2004 Elsevier B.V.
