title = "Determination of the residual stress field around scratches using synchrotron X-rays and nanoindentation",
abstract = "The residual strain field around scratches of 125 μm depth and 5 μm root radius have been measured using synchrotron X-ray diffraction. Scratches were produced using different tools in fine-grained aluminium alloy AA 5091. Residual stresses up to +1700 με were measured at the scratch tip, depending on the tool used to make the scratch. The load-displacement curves obtained from nanoindentation were used to determine the residual stresses around the scratches. It was found that the load-displacement curves are sensitive to any local residual stress field present and behave according to the type of residual stresses. This combination of nanoindentation and synchrotron X-rays has been proved highly effective for the study of small-scale residual stresses around features such as scratches.",
