Al/SiCp Metal Matrix Composites Fabricated via Friction Stir Powder Processing

Characterization of Aluminum-Based-Surface Matrix Composites with Iron and Iron Oxide Fabricated by Friction Stir Processing

Surface composite layers were successfully fabricated on an A 1050-H24 aluminum plate by dispersed iron (Fe) and magnetite (Fe₃O₄) particles through friction stir processing (FSP). Fe and Fe₃O₄ powders were packed into a groove of 3 mm in width and 1.5 mm in depth, cut on the aluminum plate, and covered with an aluminum sheet that was 2-mm thick. A friction stir processing (FSP) tool of square ...

Friction stir welding and processing

Friction stir welding (FSW) is a relatively new solid-state joining process. This joining technique is energy efficient, environment friendly, and versatile. In particular, it can be used to join high-strength aerospace aluminum alloys and other metallic alloys that are hard to weld by conventional fusion welding. FSW is considered to be the most significant development in metal joining in a de...

On the fabrication and characterization of Al5083/Al2O3 surface nanocomposite via friction stir processing

In the present study, Al5083- Al2O3 nanocomposite was successfully prepared by friction stir processing (FSP) with rotational speed of 710 rpm and travel speed of 14 mm/min. In order to improve distribution of Al2O3 particles, a net of holes were designed on the surface of Al5083 sheet. The samples were characterized by optical and scanning electron microscopy (SEM), microhardness, tensile and ...

Metal Powder-filled Polyethylene Composites. v. Thermal Properties Metal Powder-filled Polyethylene Composites. v. Thermal Properties

Thermal properties—such as thermal conductivity, thermal diffusivity, and specific heat—of metal (copper, zinc, iron, and bronze) powder-filled high-density polyethylene composites are investigated experimentally in the range of filler content 0–24% by volume. Experimental results show a region of low particle content, 0–16% by volume, where the particles are distributed homogeneously in the po...
