Abstract

The literature is a deficit of the effect of fractographic and microstructural analyses on the yield strength (δy) of experimental 7xxx alloy fabricated from Recycled Beverage Cans (RBCs). This paper aims at fabricating a novel Al-5Zn-1.5Mg-1Mn-0.35Cu alloy from RBCs and 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. [ABSTRACT FROM AUTHOR]

Abstract

• A new aluminium alloy was cast from recycled beverage can (RBC) using stir casting method. • Precipitation hardening and artificial aging treatments were done at 475 °C and 145 °C respectively. • Postmortem of the nature of fracture and substrates was conducted. • Peak yield strength (σ y) of 117.200 MPa and least of 51.212 MPa were recorded with an average extension (e) of 0.197 mm. The aim of this letter was to conduct a postmortem on the nature of fracture, substrates and possible precipitates formed in a novel experimental 7xxx alloy cast from recycled beverage cans (RBCs) and link same to yield strength (σ y) following heat treatment (HT). Fractographic investigation revealed the formation of dendrites and hardening phases such as MgZn 2 and Al 2 Mg 3 Zn 3 among others, following HT. An alloy S10 recorded the peak σ y of 117.200 MPa while S3 was the least with 51.212 MPa and extension (e) of 0.197 mm. [ABSTRACT FROM AUTHOR]
