Abstract
A method for removing casting defects () from an article () with an oriented microstructure can include locating at least one casting defect () and melting the casting defect () locally by a heat source () to a depth at least as great as the casting defect () itself. The molten material can then be solidified epitaxially with respect to the surrounding oriented microstructure of the article () in a way that the resulting solidified area is substantially free of any defect.
