Abstract EN
This work has focused on the development of a new aluminum alloy containing 4.8 wt% of Cu alloy obtained from recycled aluminium cans designed for thixoforming process.
After the step of melting and solidification of the alloy in a metallic permanent mold, samples were solution heat treated at 525°C for times ranging from 2 h to 48 h, quenched in water and followed by natural aging.
Results have shown the evolution of hardness so from them solubilization solution heat treatment was chosen for 24 h.
The best condition for aging was 190°C during 3 h.
With this data pieces were thixoforged at 580°C and 615°C corresponding, respectively, to solid fraction ( f s ) of 0.8 and 0.6.
The optimized T6 temper was applied and tensile tests were performed.
The mechanical properties obtained are compatible with those obtained for consolidated alloys processed in semisolid state (SS) and after T6 temper hardness increases from 95 HB to 122 HB and the best results were a tensile strength of 324 MPa ± 10 MPa, yield strength of 257 MPa ± 18 MPa, and an elongation of 7.1% ± 1%.
For alloys designed for thixoforming process, these results are in accordance with what was expected whereas globular microstructure, high ductility, and good performance under cyclic conditions are desirable.
