摘要： PROBLEM TO BE SOLVED: To highly accurately and continuously detect any surface flaws of sizes to be primarily inspected.
SOLUTION: Fluorescent magnetic particles are used for primary inspection for previously detecting flaw defects of a flow width of 5 μm or larger. Permeable particles, a fluorescent coloring agent, and a binder are dissolved or dispersed in a solvent to form a pasty object, and the pasty object is dried. The dried object is crushed into crushed magnetic particles having mean particle diameters between 5-10 μm. Permeable particles, a fluorescent coloring agent, and a synthetic resin emulsion are dispersed in water to form a pasty object, and the pasty object is sprayed and dried to produce spray magnetic particles having mean particle diameters between 10-15 μm. The fluorescent magnetic particles are constituted of the crushed magnetic particles of 50-80 wt% and the sprayed magnetic particles of 20-50 wt%. By this, it is possible to effectively act on flaw detection on any surface flaws and serve for a wide range of uses. Since it is possible to heighten both a S/N ratio and a slice level threshold value, it is possible to easily discriminate noise from defects at image processing. Since there are only few variations in magnetic particle luminance and a particle size distribution due to continuous use, indication patterns to flaws do not degrade to achieve effective action.

摘要： PROBLEM TO BE SOLVED: To provide an ultrasonic flaw detecting method and its apparatus, capable of stably and reliably detecting subsurface flaws in the vicinity of surfaces, even when there are disturbances of the position of the object material of flaw detection and that disturbances, such as transfer plays and variations in the echo intensity, and to provide steel products which are the results thereof. SOLUTION: A probe 1 is made to relatively move along a surface of an object material P of flaw detection at each prescribed movement pitch D to transmit ultrasonic waves W substantially perpendicular to the object material P of flaw detection from the probe 1, receive reflected waves E, and acquire flaw detection signals. Reference positions H are set, on the basis of bottom echoes G in the acquired flaw detection signals; and flaw detection signals for each movement pitch D are adjusted and combined, in such a way that the reference positions H matches to generate two-dimensional image data. Flaws in a region in front of the reference positions H in the two-dimensional image data are extracted. COPYRIGHT: (C)2008,JPO&INPIT
