摘要： An analysis controller 102 determines multi-dimensional characteristics of one or more corrosion pits 200 in equipment 104. These characteristics can include depths, widths, and/or aspect ratios of the corrosion pits 200. The controller also determines one or more stresses on the equipment 104 based on the characteristics of the corrosion that are determined. The analysis controller 102 also generates a control signal to implement one or more remedial actions to one or more of remove the one or more corrosion pits 200, repair the equipment 104, or restrict operation of the equipment 104 based on the one or more stresses that are determined.

摘要： An aspect of the present disclosure is to precisely define a constant value used in the Monkman-Grant analysis, when estimating remaining life of a high-chromium steel pipe through which high-temperature and high-pressure fluid is allowed to flow. A remaining life estimation method according to the present disclosure is particularly characterized in that a step of obtaining a constant (accelerated creep test S1) is performed in which a constant indicative of the product of a strain rate and a rupture time in the Monkman-Grant analysis is obtained by multiplying a first coefficient to transform uniaxial rupture ductility into multiaxial rupture ductility, the uniaxial rupture ductility being obtained from a specimen of the high-chromium steel pipe, a second coefficient to amend consumed life of the specimen, and a third coefficient to amend a measured pressure into an assessment pressure.

摘要： A method of non-destructive evaluation of stress corrosion cracking of structural components made of metal alloys, and a method of evaluation of the remaining lifetime of the structural component made of metal alloys are provided, in which a change in properties of the structural components made of metal alloys being used in operating nuclear power plants is measured according to the degree of atomic ordering (or short range ordering) of alloying atoms, and stress corrosion cracking of the structural components made of metal alloys is thus evaluated. The properties to be measured may be one or more selected from a group consisting of hardness, electrical resistivity and thermal conductivity.

摘要： A method of testing the oxidation resistance of an alloy comprises applying a layer of salt on the surface of the alloy (54) and placing the alloy in a furnace (56), the furnace being at a predetermined temperature of at least 1000°C and containing an oxygen containing gas. The alloy is maintained in the furnace (58) at the predetermined temperature for a predetermined period of time and then the alloy is removed from the furnace (60) and the alloy is allowed to cool to ambient temperature or other suitable temperature. These steps (54 to 60) are repeated for a number of times to maintain the salt on the surface of the alloy at a level of 0.5 to 30µg cm- 2 h -1 . The alloy is weighed periodically (52, 64) to determine the oxidation resistance of the alloy. The advantage of the procedure is that the addition of salt reduces the time to test the oxidation resistance of the alloy and the addition of the salt mimics the degradation of the alloy in a real working environment in a gas turbine engine. The alloy may be a superalloy for a gas turbine engine component or a coating alloy for a gas turbine engine component.
