Abstract:The residualstress, RS, profiles in a 6061Al-15 vol.% SiCw composite and in its unreinforced alloy have been determined by synchrotron radiation diffraction, SRD. The high spatial resolution achieved by this technique has allowed resolving the spatial dependence of all three principal components of the RS field with the sample radius. The micro and macrostress have been successfully separated revealing the differentdistribution along the sample cross section as a consequence of their different nature. In this way clear experimental evidence of theoretical works could be given
