摘要： PROBLEM TO BE SOLVED: To realize a magnetic sensor which can be miniaturized, and can measure an intensity of a magnetic field in a high temperature and radiation environment, while suppressing increase of consumption of current.SOLUTION: A magnetic core 1 is formed of a Co-Fe based soft magnetic material having a Curie temperature of 600°C or more, is formed into a rectangular loop shape, and has a narrowed section 4 at one of the long sides. An excitation coil 3 is wound around a long side where the narrowed section is not formed, and a detection coil 2 is wound around a side except the long side having the narrowed section. An external magnetic field intensity exerting to a long side direction of the magnetic core is measured by evaluating time interval difference between time intervals of a positive peak to a negative peak and a negative peak to a positive peak which are output voltage output from the detection coil, or by evaluating a ratio of the time interval difference and an excitation period.

摘要： PROBLEM TO BE SOLVED: To provide a system for evaluating a symptom before crack generation of an irradiation assisted stress corrosion crack (IASCC) generated in a structure material of a nuclear reactor, a particle accelerator or the like. SOLUTION: A third harmonic voltage value of a specimen is measured by an AC magnetization method, and the degree of IASCC sensitivity of the specimen is determined on reference to a database showing a mutual relation between the magnitude of a change of the third harmonic voltage value determined beforehand and the degree of IASCC sensitivity. Further, an eddy current method probe voltage of the specimen is measured, and the degree of IASCC sensitivity of the specimen is determined on reference to a database showing a mutual relation between a change of an eddy current method probe voltage value determined beforehand and the degree of IASCC sensitivity, and it is determined whether or not the determined degree of IASCC sensitivity is within a prescribed error range from the degree of IASCC sensitivity determined from the change of the third harmonic voltage value.

摘要： PROBLEM TO BE SOLVED: To provide a supper ODS (oxide dispersion strengthening) steel having high crrosion resistance to lead, bismuth and super critical pressure water and at the same time, the strength particularly the high temperature strength, is improved. SOLUTION: The oxide dispersion strengthening type alloy steel is produced by applying a mechanical alloying treatment to powers, with which into Fe powder, as the ratio to the total weight, 13.0-23.0% Cr powder, 3.5-5.0% Al powder and 0.25-0.45% Y 2 O 3 powder, 0.02-0.05% C powder and at least one side of 0.2-0.7% Hf powder and 0.4-1.0% Zr powder, are mixed. Among those powders, Hf or/and Zr are prevented from the agglomeration of the oxide with Al, and since the distribution of the oxide becomes fine and high density, such as 9Cr ODS steel, the high temperature strength is improved. Further, Hf or/and Zr are formed as the carbide or the oxide in the crystal grain boundary, and thus, the high temperature strength is improved by restraining the grain-boundary slipping.

摘要翻译：要解决的问题：提供对铅，铋和超临界压力水具有高耐腐蚀性的晚熟ODS（氧化物分散强化）钢，同时提高特别是高温强度的强度。解决方案：氧化物分散强化型合金钢是通过机械合金化处理制成的，其中Fe粉末以总重量计，13.0-23.0％Cr粉末，3.5-5.0％Al粉末和0.25-0.45％Y 2 3 粉末，0.02-0.05％C粉末和至少一侧为0.2-0.7％Hf粉末和0.4-1.0％Zr粉末，混合。在这些粉末中，防止了Hf和/和Zr与Al的氧化物的团聚，并且由于氧化物的分布变细，高密度，例如9Cr ODS钢，提高了高温强度。此外，Hf或/和Zr在晶界中形成为碳化物或氧化物，因此通过抑制晶界滑动来提高高温强度。版权所有（C）2010，JPO＆INPIT
