Abstract
The material used is recycled aluminum alloy. The ship’s propeller is cast through a steel mold. The macroporosity, misrun, and cold shut defects formed in the cast products of the ship’s propellers were observed for their location, geometric shape, and size. Defects are generally formed at the tip of the blade with various geometries and sizes, and shrinkage cavity defects are observed at the butt of the blade. No defects were found in the product when die mold was preheated.
