Abstract

The objective of this study was to investigate the synthesis and characterization of aluminum alloy AA8011 reinforced with various amounts (0, 4, 8 and 12 wt.-%) of fly ash (FA) particles by the stir casting method. The wettability of fly ash particles in the matrix was improved by adding 0.5 wt.-% of Mg into the solution. Fly ash particles were combined with the semi-solid aluminum solution. The microstructure and mechanical properties of the fabricated aluminum matrix composites were analysed. The optical and SEM with EDX revealed a homogeneous dispersion of fly ash particles in the aluminum matrix composites. The aluminum matrix composites were characterized by a homogeneous distribution of fly ash particles having clear boundaries and good bonding qualities to the aluminum matrix. Mechanical properties such as hardness and tensile strength improve with an increase in weight percentage of fly ash particulates in the AMCs.

Kurzfassung

Das Ziel der diesem Beitrag zurngunde liegenden Studie bestand darin, die Synthese und die Charakterisierung der Aluminiumlegierung AA8011 vorzunehmen, die mit verschiedenen gehalten an Flugasche-Partikeln mittels des Rührgießens verstärkt wurde. Die Benetzbarkeit der Flugaschepartikel in der Matrix wurde verbessert, indem 0,5 wt.-% Mg in die Lösung zugegeben wurde. Die Flugaschepartikel wurden mit einer halbfesten Aluminiumlösung vermischt. Die Mikrostruktur und die mechanischen Eigenschaften der so hergestellten Aluminiummatrix-Komposite wurden analysiert. Die optische sowie die Rasterelektronenmikroskopie mit EDX ergaben eine homogene Verteilung der Flugaschepartikel in den Aluminiummatrix-Kompositen. Die Aluminiummatrix-Komposite zeigten zudem eine klare Grenze der Flugaschepartikel und eine gute Verbindung zur Aluminiummatrix. Die mechanischen Eigenschaften, wie die Härte und die Zugfestigkeit verbesserten sich mit der Zunahme der Gewichtsanteile an Flugasche.
