Abstract
In Fall 2010, a workshop on the role and future of Fe-based Oxide Dispersion
Strengthened (ODS) alloys gathered together ODS alloy suppliers, potential industrial
end-users, and technical experts in relevant areas. Presentations and discussions focused
on the current state of development of these alloys, their availability from commercial
suppliers, past major evaluations of ODS alloy components in fossil and nuclear energy
applications, and the technical and economic issues attendant to commercial use of ODS
alloys. Significant progress has been achieved in joining ODS alloys, with creep resistant
joints successfully made by inertia welding, friction stir welding and plasma-assisted
pulse diffusion bonding, and in improving models for the prediction of lifetime
components. New powder and alloy fabrication methods to lower cost or improve endproduct
properties were also described. The final open discussion centered on challenges
and pathways for further development and large-scale use of ODS alloys.
