title = "Formation and evaluation of closed stress corrosion cracks in ni-based alloy weld metal for nuclear power plants",
abstract = "Closed stress corrosion cracks (SCCs) have been generated in nuclear power plants, resulting in the underestimationand nondetection. To solve this problem, we have developed closed-crack imaging method, the subharmonic phased array forcrack evaluation (SPACE), on the basis of subharmonic waves and phased array technique. Here, after verifying the SPACE in a realistic SCC specimen, we present a two-step method for forming deep closed SCC for a reasonable amount of time. The SCC closure was verified by SPACE. This significantly contributes to the improvement of nondestructive evaluation methods and training/educating of inspection engineers.",
