The aim of this work is to investigate the residual stresses induced by plasma transferred arc deposition of an iron-based hard-facing alloy (Norem©) on stainless steel (316L). Access to quantitative information about the residual stress state should validate the ability of numerical modelling to represent process-induced stresses in order to perform a comprehensive toughness analysis. Stress determination into different metallurgical phases by means of neutron diffraction should also provide useful information about stress repartition at the micro-scale allowing better understanding of fracture micro-mechanisms and generally advance cobalt-replacement projects.Results expected includea a detailed residual stress profile in a model specimen that can be used to complement alternative characterisation techniques and a significant enhancement of knowledge of this important technology.
