Abstract
In situ neutron diffraction measurements were performed to investigate the lattice-strain evolution around a fatigue crack under five different loading conditions (i.e. fatigued, tensile overloaded, compressive underloaded, tensile overloaded?compressive underloaded, and compressive underloaded?tensile overloaded) during fatigue crack growth. The results show that different crack-growth behaviors are closely related to the distinct strain distributions developed near the crack tip under the various loading conditions.
