摘要： On the basis of a finding that a magnetic hysteresis of a metal material, among magnetization characteristics changing with secular degradation of the metal material, shows a clear correspondence with the degree of degradation of the metal material, a change in such a magnetization characteristic is measured to estimate the degree of secular degradation of the metal material. In a typical embodiment, a superconducting quantum interference device is used to detect the magnetization characteristic of a measuring object. According to the present invention, the degree of embrittlement of a metal material used in an environment of high temperatures can be quickly detected in a non-destructive fashion so that the danger of brittle fracture of the metal material can be reliably prevented.

摘要： A method of subjecting a welded structure to heat treatment in which a tensile yield is produced on an inner surface of the welded structure and a compressive yield is produced on an outer surface of the welded structure by the steps of placing a cooling medium in the interior of the welded structure and heating the outer surface of the welded structure to cause a difference in temperature to exist between the inner surface and other surface of the welded structure. The method further includes the step of locally heating a weld by means of a heating member to improve residual stress in a localized area of the weld and repeating the improvement of the residual stress regarding another localized area of the weld.

摘要： A method of determining fatigue life of metals that are subject to the cyclic load. A metal that exhibits a half-value width that varies depending upon the degree of deformation by fatigue is melt-adhered onto a recessed portion formed in a metal of which the life is to be determined. The two metals are subjected to the cyclic load simultaneously. Then, the melt-adhered metal is irradiated with an X-ray, and a half-value width of an S-N curve of the resulting diffracted X-ray is measured, thereby to determine the fatigue life of the metal of which the life is to be estimated. The method is effective for accurately determining the life even for the metals which exhibit half-value widths that change very little depending upon the degree of deformation by fatigue.
