A New Approach to Direct Friction Stir Processing for Fabricating Surface Composites
نویسندگان
چکیده
Friction stir processing (FSP) is a green fabrication technique that has been effectively adopted in various engineering applications. One of the promising advantages FSP its applicability development surface composites. In current work, new approach for direct friction considered aluminum-based composites reinforced with micro-sized silicon carbide particles (SiC), eliminating prolonged preprocessing stages preparing sample and filling holes grooves. The proposed design tool consists two parts: an inner-threaded hollow cylindrical body; pin-less shoulder. examined respect to three important parameters: tilt angle tool, tool’s dispersing hole, plunge depth. study shows use hole diameter 6 mm depth 0.6 mm, combination tilting 7°, results sufficient mixing enforcement aluminum matrix, while still maintaining uniformity thickness composite layer. Metallographic examination Al/SiC demonstrates uniform distribution Si excellent adherence substrate. Microhardness measurements also show remarkable increase, from 38.5 Hv at base metal maximum value 78 processed matrix effect parameters was studied, consequences are discussed.

Metal matrix composites (MMCs) exhibit improved strength but suffer from low ductility. Metal particles reinforcement can be an alternative to retain the ductility in MMCs (Bauri and Yadav, 2010; Thakur and Gupta, 2007) [1,2]. However, processing such composites by conventional routes is difficult. The data presented here relates to friction stir processing (FSP) that was used to process metal ...

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...

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 ...
