摘要： PURPOSE:To enable taking by using a transfer agent having a high electrical conductivity with a fewer number of production stages by coating a release agent onto the surface of a material to be inspected which is etched by an etching liquid after polishing, then coating the specific transfer agent thereon. CONSTITUTION:The release agent 3 is coated on the surface of the material 2 to be inspected which is etched by the etching liquid after polishing and thereafter, the transfer agent 1 consisting of 50-70wt.% C and 50-30wt.% epoxy resin is coated thereon. Voids 11 and carbides 12 are deposited by the creep damages formed on the material and extremely slight defect flaws 13 are distinctly exposed when the surface of the material 2 is etched. The transfer agent 1 coated on the surface is easily stopped if the release agent 3 is previously coated on the material 2 subjected to such surface treatment. The metal defects are distinctly microscopically examined by the X-rays, reflected electrons and secondary electron rays emitted from the transfer agent 1 if the transfer agent 1 is inspected by an electron microscope.

摘要： PURPOSE:To apply uniform pressure to a test piece by enabling the pressure receiving parts and pressure chamber of the test piece to function as a piston and a cylinder respectively and feeding and discharging fluid to and from the space in the pressure chamber partitioned by the pressure receiving parts of the test piece. CONSTITUTION:The round test piece 1 equipped with the discoid pressure receiving parts 1a at both end parts penetrates a casing 2 and is so extended that the pressure receiving parts 1a slide on the side wall of the pressure chamber 3 formed in the casing 2. When a tension load is placed on the test piece 1, a pressure regulating device 7 is put in operation to admit working oil from feed/discharge pipes 6a and 6b and fill spaces A and B partitioned with the pressure receiving parts 1a with the working oil, and the hydraulic pressure of the working oil supplied to the pipe 6b is increased gradually to raise the internal pressure in the space B and push the pressure receiving parts 1a outward, so that tensile stress operates on the test piece 1. When a compression load is placed on the test piece 1, on the other hand, the pressure of the working oil supplied to the pipe 6a is increased to raise the internal pressure in the space A, and compressive stress operates on the pressure receiving part 1b of the test piece 1, so that the test piece 1 is given the uniform stress.

摘要： PURPOSE:To diagnose the service life of a structural member by operating the member having a flat protrusion at the tip for a predetermined time under high temperature and then measuring the hardness thereof at various points thereby measuring the variation of hardness due to thermal deterioration at a point where the service life is evauated with no effect of stress. CONSTITUTION:Since a turbine rotor 1 rotates at high speed under high temperature, the corner part 7 at the root of the wheel 2 of the rotor 1 is subjected to nonsteady thermal stress due to centrifugal stress and start/stop operation of turbine. When the turbine is operated for a long term under that state, high temperature thermal deterioration takes place to cause creep fatigue through repetition of the operation. The corner part 7 is set as a service life diagnostic part 7 and a protrusion 6 is provided closely thereto on the side face of the wheel 2. The protrusion 6 is in same temperature state as the diagnostic part 7. The flat part at the tip of the protrusion 6 is in low stress state and the hardness can be measured thereat. The measurements are employed in the determination of low cycle fatigue characteristics and creep rapture characteristics thus diagnosing the service life.

CONSTITUTION:An operation condition and component shape setter 1 sets border conditions for temperature and stress calculation and the nonstationary and stationary temperatures and stress of the component are calculated 2. A gamma' shape parameters is calculated 4 from an electron microscope photograph sampled by a metal structure sampler 3 and both low-cycle fatigue and creep breakage characteristics are calculated 5 by using the parameter, temperatures, and stress; and the stationary operation time and start/stop frequency of the component are set by an operation history setter 6 and both accumulation damage data on the low-cycle fatigue and creep are calculated 7 according to data on 12. Further, life expectancy arithmetic 9 is carried out by the setting 8 of the subsequent stationary operation time and start/stop frequency of the component and accumulation damage calculation 7, the diagnosis result based upon the both is displayed 10, and when the life almost ends, an alarm is generated. Consequently, a quantitative life expectancy diagnosis is taken in consideration of future operation configurations.
