| Summary: | The literature is a deficit of the effect of fractographic and
microstructural analyses on the yield strength (δ ) of experimental 7xxx
alloy fabricated from Recycled Beverage Cans (RBCs). This paper aims at correlate between fractography, microstructures, chemical compositions,
and δy with respect to heat treatment (HT) parameters. Both
intergranular and intergranular fractures were found predominantly
ductile with micro dimples. Prolonged ageing time increased the
thickness of boundaries and precipitated free zones (PFZs). Micro-voids
and flake-like patterns indicated the formation of secondary phases.
Maximum δy of 129 MPa and elongation of 16.3 % were observed in an
alloy annealed (o) at 413 °C, artificial aged (T6) at 145 °C, for 6 h. Thus,
modifications of HT process has significantly influenced the δy and
microstructure of the alloy fabricated from RBCs. Future studies should
concentrate on investigating the effect of variations in the wt. % Zn on
the mechanical properties. |
