摘要： PROBLEM TO BE SOLVED: To provide a metal glass evaluation method capable of precisely and simply evaluating the existence of the crystallization or internal flaw of metal glass by a single method, and to provide a metal glass evaluation apparatus.
SOLUTION: AC is applied to the coil brought into contact with the surface of the metal glass and, on the basis of a change in the produced eddy current signal, presence of crystallization or internal flaw of the metal glass is detected. According to such a configuration, this method which is different from X-ray diffraction method or X-ray transmission method that accompanies hazards and thermal analysis method that requires cutting of a material, and the presence of the crystallization or internal flaw of the metal glass can be evaluated safely, accurately and simply by a single method.

摘要： PROBLEM TO BE SOLVED: To provide an eddy current flaw detection probe for correcting eddy current flaw detection signals caused by the distance and inclination angle between a specimen and a coil by putting noncontact and nonmagnetic distance sensors side by side with the eddy current flaw detection measurement coil and measuring the eddy current flaw detection signals and distance sensor signals simultaneously.
SOLUTION: The noncontact and nonmagnetic distance sensors 2 for transmitting and receiving light 3 to and from the eddy current flaw detection coil 1 are put side by side, measure a signal obtained from the distance sensor 2 simultaneously with the eddy current flaw detection signals, correct the eddy current flaw detection signal caused by lift-off, and separate the eddy current flaw detection signal caused by marks and a change 4 in quality. When a plurality of distance sensors 2 are put side by side with the eddy current flaw detection coil 1, the inclination 7 of the coil is calculated by computing a signal obtained by each distance sensor 2, thus correcting the eddy current flaw detection signals precisely.
