Investigation on Hot Tearing Susceptibility of A201 Aluminum Alloy in Different Ingate Velocities and Molds

In this research, Hot tearing Behavior and susceptibility of the Al-Cu A201 aluminum alloy in different mold has been investigated. There are a lot of methods that used for hot tear tests but between all of these methods that proposed for this kind of the tests, The Ring model was employed for testing the hot tearing tendency. In order to increase the investigated parameters, wooden model designated to support different ingate velocities. Some samples that exposed to the Hot Tear were inspected by visual and NDT (None destructive) tests followed by Scanning Electron Microscopy (SEM) to study of the teared surface of the samples. The extracted results show that the number and severity of tears increased by changing the strength of mold from green sand to CO2 sand. The evaluation of the experimental results in this study showed that these results is in good agreement with the other obtained by another researchers
