IPC: G01M99/00
Filed: 1993-02-03
Abstract: PURPOSE:To measure and evaluate the degree of fatigue of a material to be inspected, for exapmle of metal, using a nondestructive inspecting method prior to micro-crack initiation which precedes destruction of the material. CONSTITUTION:Prior to micro-crack initiation, the degree of fatigue of a material to be inspected is evaluated on the basis of the data obtained by X-ray diffraction measurement nondestructive, wherein repetitive stresses of predetermined type predicted likely in the service environment of the material inspected are applied to a reference piece of the same material as that inspected, and thus the fatigue test is conducted. X-ray diffraction measurement for the reference piece takes place at a plurality of points of time during the fatigue test, and from the measuring results, a fatigue characteristic curve is obtained which corresponds to the relation between the cumulative amount of the repetitive stresses and the diffraction X ray intensity. The X-ray diffraction measurement for the specified part on the material is performed at least at two points of time in the service environment, and the change rate between the measured diffraction X-ray intensities is referenced to the fatigue characteristic curve. As a result, the degree of fatigue of the material is determined and also, if necessary, its remaining lifetime until fatigue destruction occurs.
