This thesis is about the characterization of the microstructural cracks by the EDS and EBSD technique. This investigation has been done by depostion a layer of Ni-base alloy and then a C-Mn steel layer in order to understand the physial and chemical compatibility of these two dissimilar materials. This project is designed based on the welding application in the cladding pipes.Master of materials Science and EngineeringMaterials Science & EngineeringMechanical, Maritime and Materials Engineerin
