Abstract
Abstract This article reports on the development of additive friction stir deposition techniques that use secondary feedstocks such as machine chips and damaged components to make in-field repairs at the point of need. The focus of the initial research was aluminum alloys. Preliminary studies show significant promise for the adaptation of these techniques to hard alloys including steel castings, wrought high strength steels, and titanium alloys.
