Abstract
X-ray diffraction is a well-known experimental technique for measuring residual stresses in
metallic materials. If XRD is applied to the fracture surface of a broken part it becomes a fractographical
technique, that is to say that it is possible to relate the results of the measures to the loading condition that
lead a component to fail. In this paper, after an introduction about the technique, XRD fractography is applied
to a fatigue failed diesel engine crankshaft. It was possible to determine the load that lead the crankshaft
to fail and to evidence some original aspects about the application of this technique to real machine
parts.
