Towards reliable residual stress measurements in dissimilar metal welds
The proposed experiment forms the initial studies of M. Rahman, an ILL PhD thesis student, investigating methods of improving the measurement of residual stress in dissimilar metal welds. In the proposed experiment we intend to start the process of formalising the methodology for dealing with and quantifying the errors specific to determining residual stress in dissimilar metal welds by simplifying the measurements with idealised samples. In particular, in this experiment we plan to investigate the issue of pseudo strains in association with internal material boundaries by making simple, bi-material interfaces. This work will form a key step to isolating the main sources of error. The findings will support the planned inclusion of a best practice guide for neutron diffraction measurements on DMWs in the UK nuclear industry, R6 structural integrity code.
