| Abstract Scope |
In this work, an indirect extrusion process was designed to manufacture a stainless steel reinforced aluminium composite. The design utilized a feeding mandrel to prevent the deformation of the stainless steel wire and to facilitate the embedding of the wire within the aluminium alloy during extrusion. By using this method, a 12 mm diameter 6061 aluminium alloy embedded with a 2 mm diameter 304 stainless steel wire was successfully fabricated. Energy-dispersive X-ray spectroscopy revealed that aluminium and iron elements had diffused into the interfacial layer between the aluminium-stainless steel to induce some degree of metallurgical bonding. The yield strength, tensile strength and elongation to failure of the extruded composite after solution and aging heat treatment were 343.8±5.5MPa, 405.3±5.1MPa and 18.0±1.3%, respectively. As compared to extruded aluminium, yield strength, ultimate tensile strength and elongation to failure were improved by 41.8%, 31.6% and 6.3%, respectively. This result suggests that the composite material has better strength and toughness as compared to aluminium alone. |
