Abstract
Description
Aluminium alloy is applied in a variety of products, including structural
supports, engine components, cooking utensils and beverage cans. AA6061
aluminium alloy strengthened with different percentages of clay in the range
of 2 to 8 wt.% at 75 and 150 μm was produced. SEM/EDS analysed the impact
of clay particles in AA6061 used to characterized surface morphology. XRD
analysis of the prepared samples showed aluminium silicate, silicon IV oxide
and aluminium oxide intermetallic phases at different peaks in the matrix alloy.
The result depicts enriched hardness, tensile strength and percentage
elongation of developed material to about 15.1%, 5.5% and 16.7%,
respectively. The mechanical properties revealed higher results compared with
AA6061 aluminium alloy. It was observed that intermetallic phases play a
major role in supporting the reinforcement of AA6061 aluminium alloy.
