Grain refinement and associated strengthening in laser additive repaired uranium
Source abstract
Abstract
Synchronous wire feeding laser additive repairing (LAR) was first developed for uranium to recover the geometry and mechanical properties of localised defects or damaged uranium components. Significant refined grains without evident defects were achieved in the repaired zone of the LARed uranium samples. In the heat affected zone , there is a bimodal distribution of grains which comprises finely recrystallized grains and slightly larger grains containing abundant {130} twins. The microhardness and Young`s modulus of the LAR uranium were improved by grain refinement, which suggests that LAR is a promising approach for repairing or manufacturing the high-value uranium components.
