Neutron and synchrotron radiation diffraction study of the matrix residual stress evolution with plastic deformation in aluminum alloys and composites

The evolution of the matrixresidualstress, RS, with compressive and tensile plasticdeformation in aluminumalloys and corresponding composites reinforced by alumina particles (15% in vol.) has been investigated. High and moderate strength aluminumalloys, 2014Al and 6061Al, respectively, have been stu...

The RS was determined by neutron and synchrotronradiationdiffraction in samples treated to a T6 condition and deformed from 0% to 15% plastic strain. The results show that compressive plasticdeformation relaxes the hydrostatic matrix RS of all materials to a minimum at around 2–5% plastic strain. At higher strains the hydrostatic matrix RS increases noticeably in the high strength 2014Al alloy and the corresponding composite but only moderately in the 6061Al alloy and the respective composite. On the other hand, no increase of the RS takes place after a large tensile strain. This difference can be attributed to the higher inhomogeneity of the plastic flow in the high strength matrix materials in compression testProject MAT-05-0527 from MEC, Spain.
