Reference number : GC-2017-Q4-00245, amendment number : , agreement type : G, recipient legal name : Brailovski, Vladimir (École de technologie supérieure), recipient country : CA, recipient province : nan, recipient city : Quebec|Québec, recipient postal code : nan, program name english : Collaborative Research and Development Grants - Project, program name french : Subventions de recherche et développement coopérative - projet, program purpose english : The proposed research will develop and validate a set of bulk- and surface- post-processing technologies applicable to high-temperature IN625 components produced by laser powder-bed fusion (L-PBF) - for better mechanical properties, surface finish and tolerances. _x000D_
In the framework of this project, an extended study of the post processing-microstructure-properties interrelations will be carried out. As a result, an original sequence of heat and HIP treatment will be developed to avoid precipitation of intergranular carbide particles reducing material ductility at high temperatures. Next, significant data on the high temperature mechanical properties of IN625 alloy, including creep resistance, will be generated. Moreover, a set of finishing technologies capable of significantly decreasing internal surface roughness of L-PBF tubular components will be developed, validated and prepared for industrial deployment. Three finishing technologies will be tested comparatively and in combination: electropolishing, abrasive flow machining and chemical-mechanical polishing. Finally, multifaceted metrics of the surface topology assessment and geometrical tolerancing of L-PBF components with finishing technologies will be developed to allow for reliable design and certification of IN625 components for aerospace applications. _x000D_
