چکیده مقاله:

6101 aluminium alloy, in Al-Mg-Si group, is extensively used as an electrical conductors. Its elongation as well as electrical conductivity is the major properties which should be controlled during production process of aluminium wire conductors. Magnesium and silicon contents of this alloy, both, through affecting on the volume fraction of Mg2Si precipitates and insoluble silicon inclusions in the microstructure can effectively influence on these properties. In this investigation, the influence of Mg:Si concentration ratio on elongation and electrical conductivity of the 6101 rods has been studied by standard electrical resistance and tensile tests. The chemical composition of the samples and their microstructure were respectively evaluated using optical emission spectrometry and scanning electron microscopy (SEM) equipped with energy dispersive spectrometry (EDS) analyzer. The results show that in weight percent ratio of Mg:Si=1 the elongation of 6101 aluminium rods increases to about 18 % while its specific electrical conductivity does not remarkably change. This is considered as a favourite result for produced 6101 aluminium rods which are subsequently used in production process of wire conductors through cold wire drawing.
