In general, molding or FRP ship molds can only produce 1 (one) hull shape. This is of course, contrary to the production ships which are mostly customize type (based on consumer demand) and very rarely in form mass products sister ships. The high cost allocation certainly makes economic considerations regarding shipbuilding. With aim a friendly fishing boat price, it make mainstay ease burden a...

The ASTM F-75 (Co-28%Cr-6%Mo) is widely used as a biocompatible alloy in medicinefor manufacturing implants. In this study, effect of mold preheating on the as-cast microstructure of thealloy was investigated using the solid investment casting process. Several mold preheating temperaturesof 550, 700, 850 and 1000 °C were selected at the same melt superheat. The samples were characterizedby opti...
