摘要

The NaCl-Na2CO3 salt mixture is proposed as a water-soluble core material for aluminum die-casting processes. The mechanical properties and microstructures of NaCl-Na2CO3 samples prepared by gravity casting were investigated. The salt mixtures had superior properties compared to those of the pure salts. Plastic deformation occurred during compression tests at high temperatures because the eutectic region changed from lamellar to granular. Salt mixtures with NaCl primary phase and eutectic regions were found to be the most suitable core material.
