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 determine the residual stress by sticking three elemental strain gauge on a measurement point, then thinly separating a surface layer on which the gauge is sticked, to release the stress. SOLUTION: A three elemental strain gauge 2 is sticked to a member to be measured 1, and is connected with a stress meter 4 through an electrical wire 5 for the calibration. Then a separating device 6 is installed by using an adsorbing plate in such manner that the area to which the strain gauge is sticked, properly becomes a separating part 3. Then an electrode 7 is rotated around a pivot 10 by a motor 11. On this occasion, the processing liquid is supplied through a processing liquid supplying hose, for continuously wetting the member to be measured by discharging the processing liquid from a processing water hole 8, and further the power is supplied to the electrode 7 from an electric discharge machining power source 16 while controlled by a constant-voltage controlling disc for electric discharge machining 17, thereby the electric discharge machining is performed on the separating part 3 by the rotation of the motor 11 of the electrode 7, to finally separate the same from the member to be measured 1. Then the strain is measured by the strain meter 4 to read the difference before and after the separation.

摘要： PURPOSE:To evaluate life expectancy with high accuracy by estimating a creep chart and a creep rupture chart before use from the hardness of the high- temperature equipment before use. CONSTITUTION:A creep curve is determined based upon data on a received material test result document. The obtained creep curve is used to calculate variation in creep stress with time together with the temperature of a rotor. Then a hardness variation ratio chart is determined based upon the data of the received material test result document. The ratio of hardness up to a current point at a position where the life expectancy is to be found is estimated from said chart. Then the hardness is measured and the hardness before use is calculated from the result of the estimated value. The creep and creep rupture chart before use are estimated based upon the obtained hardness before use and chemical composition entered into the material test result document. Creep damage is calculated from them. Then the use time up to now is subtracted from the time when the creep damage reaches 1. The obtained result is the life expectancy.

摘要： PROBLEM TO BE SOLVED: To enable a biaxial tensile stress test with high accuracy by a simple apparatus by gradually increasing the wall thickness of a protruding curved surface closing a cylindrical part on the single end side thereof as separating from a center axis part to smoothly continue the same to the wall thickness of the cylindrical part. SOLUTION: A cylindrical test piece 1 is formed so as to be closed by a protruding curved surface consisting of a connection part 4 smoothly continued from the single end surface 2 of a cylindrical part 5 and a test part 3. The wall thickness of the protruding curved surface gradually increases as being separated from a center axis part to smoothly continue to the wall thickness of the cylindrical part 5. Herein, the test part 3 and the connection part 4 have an almost spherical shell shape and, especially, the test part 3 protrudes as a part of a thin-walled spherical shell uniform in thickness and having the same center as the cylindrical part 5 at the cylindrical center axis part of the protruding curved surface. Since the outer peripheral surface of the test part 3 is spherical and thin, when the test part 3 receives internal pressure, the stress in the thick wall direction thereof is zero and the test part 3 receives axial tensile stress equal in two directions right-angled to the wall thickness direction, that is, equal biaxial tensile stress. Therefore, an equal biaxial tensile stress test can be performed by a simple apparatus.
