    摘要： A rail axial-force measuring method and an axial-force measurable rail which eliminate the effects of residual stresses existing in a rail and thus enables an axial force acting on the rail to be measured quickly and accurately are provided. The rail is provided with a stress sensing portion which is magnetized by a magnetizing head, and changes in the magnetization of the stress sensing portion are detected by a detection head as a voltage signal from which an axial force acting on the rail is measured. Preferably, the voltage signal is a Barkhausen noise signal and, also preferably, the stress sensing portion is constructed from a portion formed by first locally heating the rail into a .gamma.-phase region, and then causing cementite to precipitate by heat treatment at a temperature lower than the .gamma.-phase region. The axial-force measurable rail including the above-described stress sensing portion is also provided.

Preferably, the average grain diameter of the granular carbide precipitated in the texture is 0.05 to 1.0 .mu.m, and the standard deviation in grain size distribution of the granular carbide is 0.14 to 2.0 .mu.m. In another preferred embodiment, the average grain diameter of the granular carbide is more than 1.0 .mu.m and 3.0 .mu.m or less. Still preferably, the carbide is an M.sub.3 C compound.

    摘要： In a method of diagnosing the fatigue life of structural steelwork according to the present invention, a Barkhausen noise measurement is performed under the condition of 5 .mu.m.ltoreq.d.ltoreq.1 mm where d is the detection depth of Barkhausen noise, by using a magnetic head constituted by an air-core coil detection head and a magnetic excitation head obtained by winding a copper wire such as an enameled wire on a U-shaped core made of a soft magnetic material such as a silicon steel sheet or an amorphous magnetic material. The degree of fatigue damage of a target measurement portion is diagnosed using the root-mean-square (RMS) voltage or voltage amplitude value of the Barkhausen noise. According to this method, the degree of fatigue and degradation by stress and strain in the structural steelwork can be accurately diagnosed prior to development of cracking without any limitation on diagnostic locations. A member of steelwork having a life diagnostic function is obtained by mounting the above magnetic head on a brace- or wall-like vibration-damping device made of very low-yield steel. According to this member of steelwork, the wall or covering material of a bridge or the like need not be removed even in practicing a fatigue life diagnosis. The degree of fatigue degradation in structural steelwork can be easily and accurately diagnosed prior to development of cracking even in a location where an operator cannot access due to the structural limitation.
