Extract

X-ray diffraction observation of the material internal structure beneath fracture surfaces provide fracture analysists with useful information to investigate the conditions and mechanisms of fracture. X-ray fractography is a generic name given to this technique. In the present study, the residual stress on the fracture surface of the compact tension specimens for toughness tests was measured by X-ray diffraction. The effects of notch-tip radius and tempering temperature on the fracture toughness are discussed based on the results of X-ray fractography and fracture micromechanisms.
