106338 - Advances and Challenges in Powder Metal Hip Processing for the Production of Large Components 

There has been a significant movement in advancing the use of large hot-isostatically pressed (HIP) powdered metal parts in various industries recently.  This is driven by a desire to reduce lead times, generate near-net shaped components, eliminate welds, improve inspection characteristics, and to address other constraints for applications where  large forgings and castings are currently used in several industries. 

 

Much of this interest in large HIP technology is currently being driven by the near-term commercialization of small modular reactors (SMRs) and advanced reactor (ARs)  throughout the world, but particularly within the USA.   A consortium within the USA has been investigating the design of a large, 4.05m diameter x 4m length HIP for several years now and hope to move toward manufacture of a large HIP unit within the next 18 months.  Similarly, in the UK a slightly larger HIP unit (~4.5m) referred to as Titan is also being considered.  Interest is also growing in other countries including Korea, Sweden, and Japan towards design and production of a large HIP unit to support nuclear and other applications.

 

This paper is an attempt to summarize recent advancements in developing an ultra-large HIP system and discuss challenges in developing HIP equipment of this scale.
