In this research, the applicability of several metal hydrides as neutron moderator and shielding for D-D fusion sources has been investigated by MCNPX code. The results have been investigated in three steps to find the materials with lower thermal, fast and total neutron fluxes than conventional shielding materials. The results show relative advantages of LaNi5H6, VH, TiH2, TaH, Mg (BH4)2, YH2,...
The basic manufacturing processes of cellular materials have been briefly noted as well as the metal foam properties. The most widely used are the aluminium foams due to the following properties: very good insulation (thermal insulation and sound absorption), low density (mass), high specific rigidity in sandwich structures, very good impact damping, corrosion resistance, non-flammability, very...
در این پژوهش، با استفاده از امواج مافوق صوت نانوکامپوزیت زمینه آلومینیومی تقویت شده با نانوذرات اکسید سیلیسیم (sio2) تولید شد و سپس با استفاده از روش فوم سازی مستقیم مذاب و با به کارگیری عامل فوم ساز هیدرید تیتانیم (tih2)، فوم نانوکامپوزیتی al-sio2 تولید گردید. در ادامه، بررسیهای ریزساختاری جهت اطمینان از تولید فوم نانوکامپوزیتی و ارزیابی نقش نانوذرات بر مورفولوژی و ضخامت دیواره سلولها بهوسی...
Abstract This work aims to evaluate the cell structure of aluminium foams blown by using foaming mixture subjected under ball milling and heat treatments. paper presents study on effects various pre-treatment foamed (Al) fabricated via melt route. also demonstrates how method can be used fabricate small-sized Al foams. Prior melt, containing TiH2 was pre-treated treatment in four different ways...
Closed-cell aluminium foams with different compositions have been manufactured starting from powders and also characterized a morphological point of view by means compressive tests in order to determine mechanical properties. Circularity, equivalent diameter, average porosity area such calculated the analysis cross-sections as well specific energy absorption compression tests. Samples higher am...
