Tensile specimens of nonflammable AZ91D Mg alloy were fabricated in this study via cold chamber die-casting process. Dimensions of tensile specimens were 25mm in length, 4mm in width, and 0.8 or 3.0mm in thickness. Microstructure observation was conducted before and after tensile tests at room temperature. In the die casting process, various injection distances from 150 to 260mm were employed t...

Among many factors which affect the dimensional accuracy of dental castings, several mechanical factors have been selected and studied theoretically and experimentally by the authors1-4). The analytical method employed in those studies showed clearly the effects of mechanical conditions on the deformation of wax patterns and castings in molds during the casting process. The results of the analy...
