This volume covers current research findings and engineering applications of X每ray methods by the Japanese X每ray group members. The first part of the volume deals with fundamental problems in the methods for X每ray stress measurement. Phase stresses in the constituent phases of ceramic composites and ceramic-fiber reinforced metal-matrix composites are separately measured by X每rays, while three-dimensional stresses and thermal stresses in composites measured by X每rays are compared with the theoretical and numerical analyses. This work will therfore provide significant information for designing high-performance composites. Other topics covered include synchrotron X每ray radiation and the analysis of X每ray data by the Guassian curve method.
Part two is devoted to the application of X每ray diffraction methods for various engineering purposes, the residual stress and half-value breadth (the full width at half the maximum) of the diffraction profiles being the two main X每ray parameters utilized in those applications. Chapters are included on X每ray fractography, a powerful technique for failure analysis, which is applied to the brittle fracture of ceramics and to the fatigue fracture of steels under various service conditions.
