This work aimed to study the deformation characteristics and microstructure of AA6063 aluminum alloy component with complex shape manufactured by cold orbital forming processing. The material flowing behavior was analyzed Finite Element (FE) simulation experiments were carried out using bar blank different lengths. boss zone cut from formed samples observed scanning electron microscopy (SEM) ba...

The b-Al5FeSi intermetallic phase and coarse Mg2Si particles have negative effects on extrudability and workability of 6xxx Al alloys billets. To achieve extruded products with a high surface quality, the as-cast billets are heat-treated before extrusion. During heat treatment, the undesired intermetallic particles, i.e., b-AlFeSi platelets are transformed to rounded a-Al(FeMn)Si intermetallic ...

––The solute clusters and the metastable precipitates in aged Al-Mg-Si alloys have been characterized by a three-dimensional atom probe (3DAP) and transmission electron microscopy (TEM). After long-term natural aging, Mg-Si co-clusters have been detected in addition to separate Si and Mg atom clusters. The particle density of β′′ after 10 h artificial aging at 175°C varies depending on pre-agin...

In this study, as much as 10 and 15 wt.% nanosized silicon and carbon (Si+C) were reacted with (Mg+2B) at 650°C and 850°C, respectively, for 1 hour. The phase formation, surface morphology and superconducting properties of these samples were evaluated. The relative peak intensity as calculated from the XRD patterns indicates the formation of large Mg2Si volume fraction at low sintering temperat...

The aim of this study is to investigate the electrochemical corrosion behavior Al-Si automotive alloys with different levels Si doping in 0.1 M NaCl solution at room temperature. was performed by method, using potentiodynamic polarization and impedance spectroscopy techniques. condition surfaces characterized both optical scanning electron microscopy. Both EIS Tafel analyses revealed that resis...
