Summary on Grant Application Form |

The aim of this project is to develop a better basic understanding of microstructural evolution and the development of internal stress in the near weld zone during inertia welding of Ni base superalloy. This will be achieved through direct microstructural and internal stress measurements and computational modelling. The aim is to construct a thermo-mechanical process model able to predict the evolution of the thermal and stress profile over the welding process. This model will be backed by direct measurements of the 3D residual stress state by neutron diffraction and metallographic characterisation. Once developed, a validated finite element model of the welding process will enable tighter control over the processing parameters in order to optimise the weld microstructure and the residual stresses. In addition to the as-welded state, the analysis will be extended to the definition of suitable post weld heat treatment procedures.
