Abstract

Near-net-shape powder consolidation technology has been developing over the past 30+ years. One relatively recent example is production of hexagonal shaped beryllium mirror blanks made for the James Webb Space Telescope. More cost saving examples, specifically from the past decade, utilizing growing experience and lesson’s learned whether from a mirror substrate or structure will be discussed to show the latitude of production technology. Powder consolidation techniques include Hot Isostatic Pressing (HIP) for either round or shaped blanks and Vacuum Hot Pressing (VHP) consolidation for round blanks. The range of sizes will be presented to further illustrate the latitude of current production capability.
