Spatially resolved positron annihilation spectroscopy friction stir weld induced defects
2010/10/12
A friction stir welded (FSW) Al alloy sample was investigated by Doppler broadening spectroscopy (DBS) of the positron annihilation line. The spatially resolved defect distribution showed that the mat...
