Effects of Alloying Additions and Cooling Rate on the Microstructures and Mechanical Properties of the Cast Al-Mg-Si Alloys
Cast aluminum alloys are widely applied for the transportation industry. Alloys with silicon and magnesium as the main alloying elements are the most important of the aluminum casting alloys because of their high fluidity. However, Al-Si-Mg alloys have exhibited medium strength level at room and, especially, at elevated temperature. Recently, new casting alloys with high magnesium and silicon h...

چکیده: در این تحقیق، برخی خواص فیزیکی و مکانیکی لوبیا قرمز به-صورت تابعی از محتوی رطوبت بررسی شد. نتایج نشان داد که رطوبت بر خواص فیزیکی لوبیا قرمز شامل طول، عرض، ضخامت، قطر متوسط هندسی، قطر متوسط حسابی، سطح تصویر شده، حجم، چگالی توده، تخلخل، وزن هزار دانه و زاویه ی استقرار استاتیکی در سطح احتمال 1 درصد اثر معنی داری دارد. به طوری که با افزایش رطوبت از 54/7 به 12 درصد بر پایه خشک طول، عرض، ضخام...
15 صفحه اولEffect OF SI and AL on the Microstructure, Mechanical Properties and Machinability of 65CU-35ZN Brass
Relations between the microstructure, mechanical properties and machinability of as-cast 65Cu-35Zn brass with various amounts of Al from 0 to 4.72 and Si from 0 to 3.62 wt% were investigated. Both Si and Al initially enhanced the UTS and toughness of the brass samples, which led to improvement in machinability due to a reduction in the main cutting force. A duplex brass with random oriented α p...
متن کاملSynthesis and mechanical properties of nanostructured Mg-Al-Nd alloys
In this work, nanostructured Mg-Al-Nd alloys were successfully fabricated using mechanical alloying method. Phase structures of the milled powders and the extruded rods were examined using X-ray diffraction (XRD) and the microstructures were observed using a transmission electron microscope (TEM). The element distributions were also examined by an energy dispersive spectroscopy (EDS) system. Th...
متن کاملStructure and properties of Al–Mg mechanical alloys
Mechanically alloys in the Al–Mg binary system in the range of 5–50 at.% Mg were produced for prospective use as metallic additives for propellants and explosives. Structure and composition of the alloys were characterized by x-ray diffraction microscopy (XRD) and scanning electron microscopy. The mechanical alloys consisted of a supersaturated solid solution of Mg in the aluminum phase, phase ...
