Abstract
The repair/modification method for metallic substrates according to the present invention includes: a step for preparing a metallic substrate having a first region that is divided in an in-plane direction of the substrate, the first region containing a defect and/or a structurally discontinuous portion; and a step for repairing the defect and/or modifying the structurally discontinuous portion by pressing a friction tool which does not have a probe against a top surface of the first region while rotating the friction tool so as to generate frictional heat while pressing on the top surface.
