Note (General): In the die casting process,it is difficult to prevent porosity in products. Porosity has undesirable influence on mechanical properties such as strength of components and resistance to air leakage of pressure vessels. Recently, 出ePRPC (Porosity Reducing Post Compression) method is adopted as a secondary process to deal with porosity. The PRPC process has the potential for improving productivity because it allows the impregnation process to be eliminated or reduced. In仕lIsstudy,th e improvement of tensile strength by applying the PRPC process was investigated. The porosity inside die回stspecimens was observed nondestructively by X-ray computed tomography (CT) to examine the reduction e伍ciencyof porosity by applying the PRPC process. It was shown that PRPC with permanent strain of about 10% at the temperature of 300 degrees reduces porosity by approximately half. In addition, the tensile strength could be improved by optimizing the compression direction.
