Regulative effect of Mg/Si ratio on microstructure evolution and mechanical properties of cast Al-Li-Mg-Si alloys

Effect 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...

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...

Influence of Rolling Temperature on Microstructure and Mechanical Properties of Cryorolled Al-Mg-Si Alloy

An effect of rolling temperature on the mechanical properties and microstructural evolution of an Al-Mg-Si alloy was studied. The material was rolled up to a true strain of ∼0.7 at three different temperatures viz; room temperature, liquid propanol and liquid nitrogen. The liquid nitrogen rolled sample exhibited superior properties with a yield and tensile strength of 332 MPa and 364 MPa, respe...

Synthesis 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...
