摘要： A method for determining the thermal material properties of metal shaped parts from a model is disclosed, which describes the thermal material properties of the metal shaped part. At least one thermodynamic parameter (p) is formed as a linear combination consisting of at least one base function (hi) and of at least one weighting factor (gi), whereby the base function (hi) describes the thermal material properties, and the weighting factor (gi) takes the influence of the alloying elements on at least one thermodynamic parameter (p) into account. The method makes it possible to conduct a sufficiently precise determination of the thermal material properties with a smaller time requirement.

摘要： It is disclosed a method of determining the exposure temperature of Al and Cr of a null/nullnull MCrAlY-coating after the use in a high temperature environment, the null/nullnull MCrAlY-coating (6) exhibiting a non-equilibrium null/nullnull-microstructure at a temperature lower than the temperature during operation and the depletion of chromium from the null/nullnull-MCrAlY-coating (6) still allows the null-Cr phase to form. The coating conductivity and permeability by means of a multifrequency eddy current system is measured at different locations of the component and from the measured conductivity and permeability the exposure temperature of said different locations of the components is determined.

摘要： A nondestructive evaluating method for aged deterioration in austenitic stainless steel comprises an information obtaining step for previously obtaining a relationship between an applied stress null and the first ratio Ms/nullH* between a saturation magnetization Ms and a pseudo susceptibility nullH* based on reference minor hysteresis loops obtained by applying stresses null, respectively, correspondingly to a result of a tensile test for the same kind of material as an evaluation target. In a measuring step, values of the first ratio Ms/nullH* are obtained as measured values from measured minor hysteresis loops obtained by measuring the evaluation target. In an evaluating step, the relationship between the applied stress null and the first ratio Ms/nullH* is compared with the measured values, thereby evaluating aged deterioration of the evaluation target. The minor loops are obtained by stepwise changing a magnetic field amplitude Ha within a range of a magnetic field intensity lower than a saturation magnetization.

摘要： It is disclosed a method of measuring the thickness and/or the depletion of Al and Cr of a null/nullnull MCrAlY-coating after the use in a high temperature environment, the null/nullnull MCrAlY-coating (6) exhibiting a non-equilibrium null/nullnull-microstructure at a temperature lower than the temperature during operation. Before the coating (6) conductivity by means of a multifrequency eddy current system is measured a heat treatment is applied to transform the non-equilibrium null/nullnull-microstructure to a equilibrium microstructure having a null-Cr phase. Subsequently the Al and/or Cr depletion of the coating (6) from the coating conductivity and permeability is determined.

摘要： A new austenitic stainless steel contains 0.1-1.0 mass % of Si and not more than 0.003 mass % of Al. Nonmetallic inclusion dispersed in a steel matrix is converted to MnOnullSiO2nullAl2O3 containing not less than 15 mass % of SiO2 and not more than 40 mass % of Al2O3. During steel making, molten steel is covered with basic slag and strongly deoxidized with a Si alloy whose Al content is controlled not more than 1.0 mass % in a vacuum or non-oxidizing atmosphere. The austenitic stainless steel sheet can be formed to an objective shape without occurrence of cracking due to its less crack-sensitivity and good formability.
