Abstract
72655S03-I Reduced-activation, oxygen dispersion strengthened (ODS) ferritic/martensitic steels are the primary candidates for first wall and blanket structural applications for future fusion reactors. However, current ODS steel manufacturing is not cost effective and yields anisotropic properties with bamboo-like grain structure. This project will develop innovative, CVD coated, nanoengineered ODS powders, along with technology for their conversion to ODS ferritic/martensitic steel. The new, low cost manufacturing technique will use nanoengineered particulates, with built-in nanostructural features, that are processed into final articles via powder metallurgy techniques such as press-extrude and press-forge consolidation. Phase I will involve the chemical vapor deposition of iron carbonyl, chromium carbonyl, tungsten carbonyl, or yittrium isopropoxide on iron seed particles. The subsequent consolidation will result in improved control over dispersant size, composition, distribution, and uniformity. Commercial Applications and Other Benefits as described by awardee: New, higher strength, high temperature ferritic steels should have application to nuclear, fusion, and other power generation system construction. Additional applications include turbine engines, industrial heat treating furnace structures, and glass making equipment. The new fabrication route should enable more precise control over material microstructures.
