Deformation behaviour of 2017 nanostructured aluminium alloy

nr katalogowy: 73475

The bulk nanostructured materials are attractive for various structural applications in the aerospace and automobile industries due to significant improvements in mechanical properties. They are usually produced in the top-down approach by severe plastic deformation (SPD) processes such as hydrostatic extrusion, equal channel angular pressing, high pressure torsion, accumulative roll bonding, cyclic extrusion-compression [1÷4]. SPD hydrostatic extrusion processes are particularly attractive for commercial applications because there is necessity for rivets and other parts manufacturing in aerospace industry. The hydrostatic extrusion has been shown to produce nanocrystalline (NC) and ultrafine grained (UFG) structures in titanium, Al-alloys, Cu and Cu-alloys, iron, austenitic steel, and nickel [1, 5÷8]. Precipitation hardening Al alloys (2XXX, 6XXX, and 7XXX series) are an important class of materials due to their perfect exploitation and technological properties. The components made of 2017 and 2117 alloys are the most widely used in aircraft construction because they have a high-strength and they are suitable for use with aluminium alloy structures. The nanostructured screw-bolts develop a greater shear strength than regular 2017 ones and are believed to be used in locations where extra strength is required. The precipitation hardening Al alloys offer possibilities for achieving high strength and ductility through SPD nanostructuring and subsequent heat treatment approach [9]. Recent studies indicate that the SPD processing at room temperature (RT) of precipitation hardening Al-Mg-Si alloy (in supersaturated condition) resulted in strain-induced precipitation of second phase particles due to the large number of defects generated during deformation and consequently higher density of nucleation sites [10]. However, the formability of such materials is generally poor due to their limited ductility, and processing technology opti[...]
