| Summary: | At present, the usage of aluminum is widely used. The recycling process is needed to
respond to the government's call for a green earth campaign cause of the lack of
mineral resources on this earth. The direct recycling method is one of the recycling
method to reduces cost and energy consumptions. The aim of this study to determine
the effects of quenching and aging on mechanical and physical properties of recycled
AA6061 aluminum chips. Subsequent from this, the optimum of quenching and
aging time and also the mechanical and physical properties were studied . In this
study, the surface morphology on the specimen shows a positive results through the
length of porous become smaller. The best porosity, density and water absorption is
1.95%, 2.55 g/cm3 and 0.77 %. On the micro-hardness Vickers, the increasing
percentage of the micro-hardness is about 19% from a preference value. Meanwhile,
for the compression strength the increasing percentage of the compression strength is
17% also from a preference value. From all data were obtain, the optimum quenching
and aging time is 8 hours quenching and 10 hours of aging. With this optimum, the
reducing of energy consumptions and cost will be obtain. |
