در این تحقیق فوم آلومینمی سلول باز با استفاده از روش ریخته گری نفوذی تولید شد. به عنوان فضا ساز در ساختار نهایی فوم از گوی های سرامیکی که شامل ترکیبی از nacl ماسه کایولن و اب بودند استفاده گردید. کایولن به عنوان عامل اصلی شکل دهنده و نگهدارنده گوی ها نمک و ماسه برای بهبود قابلیت فروپاشی گوی ها در قطعه نهایی مورد استفاده قرار گرفتند. گوی ها در سه گروه مختلف با اندازه های 3، 5 و 7 میلمتر تولید شد...
A layered gradient aluminum foam was prepared by powder sintering with sodium thiosulfate (Na2S2O3) particles as the cell-forming agent. By cutting, polishing and observing under a microscope, it found that were not completely melted after but only combined surface melting. Based on quasi-static compression test macroscopic diagram of sample during deformation, mechanical properties studied, th...
Powder metallurgy (PM) is a primarily used because of its relatively close capability and cost-achievement ratio. The automotive industry considered major market for the powder industry, as it necessitates products having superior mechanical or part implementation on global level. PM technology undergoing considerable changes in manufacturing materials research automobile technologies transitio...
Aluminum hybrid metal matrix nanocomposites (Al/SiC/TiO2) were synthesized through a microwave-assisted powder metallurgy process, and their evolved microstructure mechanical properties investigated. The Al/SiC/TiO2 prepared by reinforcing aluminum (Al) with fixed amount of silicon carbide (SiC) nanoparticles (5 wt.%) varying concentrations titanium dioxide (TiO2) (3, 6, 9 wt.%). morphology res...
A worker with occupational exposure to aluminum powder developed asthmatic symptoms three years and six months after starting work. Skin tests (prick and intradermal) to aluminum chloride (AlCl3) were negative. Inhalation challenge test with 10 mg of aluminum powder and 10 mg/ml of AlCl3 solution induced an early asthmatic response. Sodium cromoglycate pre-treatment reduced AlCl3-induced bronch...
