<P>PROBLEM TO BE SOLVED: To provide a method for producing a specimen for non-destructive inspection, which can introduce a crack of an imagined size on an imagined place and is excellent in production yield of the specimen. <P>SOLUTION: In a method for producing a specimen for non-destructive inspection, which produces a specimen 1 for calibration by introducing a crack 3 to be a reference to the same metal material 2 simulated to an actual machine in order to perform the non-destructive inspection of the actual machine, residual compressive stress is previously applied to a surface B other than a place A into which the crack 3 of the metal material 2 is to be introduced. <P>COPYRIGHT: (C)2012,JPO&INPIT |
