Residual stress data for T6 AlSiCuMg cast wedges determined by neutron diffraction

Residual stress data measured in cast AlSiCuMg wedges in the T6 condition by neutron diffraction at POLDI (PSI) and ENGIN-X (ISIS). The wedges were measured at POLDI in three orthogonal directions corresponding to the height of the wedge (x) the depth of the wedge (x) and cross sectional thickness of the wedge (y). The gauge volume was 4 mm cube. The stress-free reference was an identically made wedge which had been cut into a reference comb be electro discharge machining. The comb was measured at ENGIN-X using a 2 mm cubic gauge volume. The comb was mastered to the sample measurements using a reference powder measured at both locations so the positionally dependent residual stress could be calculated.
