Abstract

AA6061/Al alloy chips of different size and fly ash particles have been recycled using the solid state process. The effect of chip size and fly ash content on the microstructure, mechanical and wear properties of the recycled AA6061/Al two phase composites were investigated. Microstructural characterization revealed a uniform distribution of fly ash particles in recycled composites with fine chips and a good interface between fly ash particulates and AA6061/Al two phase matrixes. According to mechanical and wear results, the incorporation of fly ash particles in the AA6061/Al two phase matrix caused reasonable increase in hardness, compressive strength, and wear resistance. On the recycled composites fine chips, the destructive action of the steel ball was very limited compared to that of the Al ₂O₃ ball.

Kurzfassung

Unterschiedlich große Späne aus Aluminium und der Legierung AA6061 sowie Flugaschepartikel wurden mittels Festphasenprozesses recycelt. Es wurden die Wirkungen der Spangröße und des Flugascheanteils auf die Mikrostruktur sowie die mechanischen und Verschleißeigenschaften des recycelten AA6061/Al Zweiphasenkomposites untersucht. Die Mikrostrukturcharakterisierung ergab eine gleichmäßige Verteilung der Flugaschepartikel im recycelten Kompositwerkstoff mit feinen Spänen und einer guten Phasengrenze zwischen den Partikeln und der zweiphasigen AA6061/Al-Matrix. Entsprechend der mechanischen und der Verschleißtestergebnisse ergab die Einbringung der Flugaschepartikel in die Zweiphasenmatrix eine akzeptable Erhöhung der Härte, der Druckfestigkeit and des Verschleißwiderstandes. Die zerstörende Wirkung einer Stahlkugel auf den recyelten Kompositwerkstoff aus feinen Spänen war im Vergleich zu der einer Al₂O₃-Kugel sehr begrenzt.
