HOT ISOSTATICALLY PRESSED BODY AND HOT ISOSTACTIC PRESSING METHOD

摘要

PROBLEM TO BE SOLVED: To provide a method for stably supplying members excellent in corrosion resistance by improving a HIP (hot isostatic pressing) treatment method.;SOLUTION: In a pressed body by a hot isostactically pressing, the thickness of a hardened layer by impurities in the surface is ≤50 μm. The pressed body is manufactured by packaging a work with at least three sheets of tantalum, zirconium, or the like, which are getters of carbon, oxygen and nitrogen, and performing the hot isostactic pressing.;COPYRIGHT: (C)2003,JPO
