The oxide film on the scrap surface is one of primary sources inclusions in aluminum melt. Understanding evolution films melt an important step for developing efficient recycling technologies and controlling quality product. In present study, we studied behavior were introduced via alloy scraps into melt, micro-morphology composition analyzed by scanning electron microscope energy spectrum. Res...

To study the effects of warm laser peening (WLP) on the thermal stability and mechanical properties of A356 alloy, the samples were treated by WLP using a Nd:YAG solid-state laser and temperature control device. The residual stress, micro-hardness and microstructures of samples treated by WLP were observed. The result shows that the temperature significantly affects the strengthening effect of ...

The space holder process (SHP) is a useful and common technique to obtain metal foams. However, an important question remains unsolved: Would the quality of salt affect properties aluminum foam obtained? In this paper, removable preforms two types (refined unrefined) were infiltrated with A356 alloy foams different pore sizes. interaction preform-metal was studied from analyzing morphological s...

The A356 aluminum alloy is a very commonly used in the automotive industry, for parts such as pistons, cylinder heads, and connecting rods, which mechanical properties can be effectively increased by anodizing. In this work, oxide layers were formed oxalic acid solution with defined parameters on then studied using novel combination of scanning electron microscope (SEM) in-situ nanoindentation....
