ISOSTATIC HOT PRESSING

摘要

An isostatic hot-pressing system has been developed at 15,000 to 30,000 psi for large compacts. Process demonstrations have illustrated the practicality of the system with eight-inch-diam¬eter bars at 2000°C and twelve-inch-diameter bars at 1200°C. Furthermore, the data indicate that a modification of the exist¬ing equipment will provide capacity to forty inches in diameter at 2500° C and 30, 000 psi.
