Abstract

Aluminum-Silicon alloys have a wide application in different industries. AS5U3G aluminum alloy is a hypoeutectic Al-Si alloy, in which silicon and copper are the main alloying elements. Silicon increases castability and resistance to hot tearing of the alloy. Copper increases high-temperature tensile strength and improves the machinability of the alloy. Therefore, this alloy has been widely used in the manufacturing of automobile engine parts. Modification treatment by strontium has a major influence on the properties of the alloy. In this research, electrical conductivity has been used to evaluate the modification and dendrite arm spacing (DAS) of the alloy as a non-destructive testing. Different levels of strontium have been added to the melt and electrical conductivity of the samples measured after solidification.The results indicate that electrical conductivity increases with modification improvement and its maximum value is obtained at full-modified state. Therefore, the modification rate of the alloys may be estimated before melt pouring and casting by measuring electrical conductivity. Non-destructive evaluating of DAS has also been done in both modified and un-modified samples.
