Abstract :
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.
