Mapping the stress & phase evolution across the interface between dissimilar metallic alloys – Phase 3

Abstract: Spray forming of thick claddings of dissimilar metallic alloys that have different material properties give rise to significant residual stresses developed across the interface that can cause macroscopic distortions and cracking which may lead to delamination during and/or after manufacture. In this study, we intend to use ex situ neutron diffraction to map the stress and phase distribution evolution in dissimilar steel preforms when subjected to thermal cycling to assess the integrity of the interfacial bonding. Crack propagation/formation along the interface will also be explored using neutron imaging. This will assess the capability of the preforms to withstand downstream thermo-mechanical processing in a quantitative manner and provide guidance on the limits of process parameters to spray form dissimilar metallic alloy components with high integrity interfacial bonding.
