Abstract
The paper presents study results on AlSi11 alloy, which was obtained by extruding chips obtained from turning process. Mechanical properties from uniaxial tensile test and Vickers hardness test were determined. The influence of aging conditions on mechanical properties was invetsigated.
Highlights
Recycling of light metals is mainly carried out by melting
Silicon is subjected to spheroidization during siliconization, which translates into final mechanical properties
As a result of aging, the over-saturated solution contains clusters rich in Si and Mg, which are subsequently transformed into zones GP and metastable, coniferous β"
Summary
The paper presents study results on AlSi11 alloy, which was obtained by extruding chips obtained from turning process. The popularity of silumin in the casting industry is a natural consequence of their exceptional properties such as good durability, crack resistance and low casting shrinkage. Thanks to these features, AlSi alloys have been widely used in the automotive industry. As a result of aging, the over-saturated solution contains clusters rich in Si and Mg, which are subsequently transformed into zones GP and metastable, coniferous β". These particles are responsible for a significant increase in the strength of the secretory strengthening process. In quaternary alloys such as AlSiCuMg, there may be additions of Q and Θ' [9]
