 note = {Nondestructive evaluations of iron-based material are investigated using magnetic sensors for magnetic Barkhausen noises and leakage flux sensors, and surface deformation detections by a CCD-Laser device. The tensile stress of 0.1% was successfully detected for ferromagnetic materials as A533B via lattice imperfection change, and 2% for paramagnetic materials as SUS304 via martensitic transformation. The surface deformation was detected as small as 10 urn for any mm thick plates by the CCD-Laser device, which corresponds to 0.01% residual strains., text, application/pdf},
