Powder Hot isostatic pressing (P-HIP) is a manufacturing process that involves the simultaneous application of high temperature and pressure to consolidate powders into netshape products.
A programme of detailed research is required to understand the formation mechanisms of oxides and carbides at the prior particle boundaries (PPBs) in certain alloys, as a function of the powder quality and the atomisation route.
Other metals and alloys, with higher oxygen solubility levels, can benefit from the oxygen pick-up to improve their strength at the expense of the ductility and other properties.
This project will focus on the use of HIPing to support manufacturing in the nuclear industry for both fission and fusion reactors.
Materials such as Oxide Dispersion Strengthened (ODS) steels and tungsten will be the subject of research due to their critical importance to this industry.
