摘要： PURPOSE:To enable highly accurate measurement of the degree of deterioration in material, by detecting only information indicating changes in the electric conductivity of a sample based on the detection output as obtained when a current is supplied to a coil for generating eddy current and a coil for magnetization. CONSTITUTION:Coils 2, 3 and 5 respectively for generating eddy current, for detection and magnetization are arranged on a metal sample 1, an alternating current is supplied to the coil 2 from an exciting power source 41 to induce a fine voltage in the coil 3 and the voltage is synchronously detected as reference signal for a signal of a power source 41 with a lock in amplifier 42. When compared with an output as obtained when the sample 1 is separated from the coils 2, 3 and 5, an output of the amplifier 42 shows a change according to the degree of deterioration in material of the sample 1. The changes in the output are mixed with those in magnetic permeability and in electric conductivity of the sample 1. Under such a condition, when a current is supplied to the coil 5, the sample 1 is magnetized to change in the magnetic permeability and the amplifier 42 converts this changing output in the coordinates to output only the portion of the electric conductivity containing no effect of the magnetic permeability. Thus, the degree of deterioration is evaluated based on changes in the electric conductivity alone thereby enabling highly accurate measurement of the degree of deterioration.

摘要： PROBLEM TO BE SOLVED: To provide a method of noncontactly determining a creep damage and an embrittlement as a thermal damage generated in a heat-resistant steel, especially a high Cr steel, and evaluating a degradation in the heat-resistant steel, and to provide a method of evaluating degradation in a turbine using the method.
SOLUTION: The method of evaluating degradation in the heat-resistant steel calculates an area ratio of a deposition generated on a surface of the heat-resistant steel to be inspected, and determines the degree of the embrittlement in the heat-resistant steel from the area ratio of the deposition generated on the surface of the heat-resistant steel on the basis of a previously-created graph for indicating a correlation between an embrittlement index and the area ratio of the deposition generated in the heat-resistant steel. The degradation evaluation method calculates a number concentration of voids generated on the surface of the heat-resistant steel, normalizes it by use of the multiaxial degree of the heat-resistant steel, and determines the degree of the creep damage in the heat-resistant steel from a value as the number concentration of the voids generated on the surface of the heat-resistant steel normalized by the multiaxial degree on the basis of a previously-created graph for indicating a correlation between a lifetime ratio of the heat-resistant steel and the number concentration of the voids normalized by the multiaxial degree.
