Abstract
In this study, the simultaneous effects of Zn addition and critical gate velocity on hot tearing susceptibility of A356 and A206 aluminum alloys were investigated. In order to investigate these two parameters, ingate velocities of 0.5, 0.75, 1, 1.5 m/s were taken into account. After performing the casting process, the samples were investigated by visual examination, and scanning electron microscopy. In order to quantitative evaluation of results, ProCast software were used. The results of the present study showed that increasing the Zn content for alloy A356, had no effect on hot tearing susceptibility of this alloy, and while with increasing the Zn content from 0.01 to 2.8 wt. %, the number and severity of the tears were increased.
