Microstructural assessment of additive manufacturing parts towards aeronautic application

Abstract

The aeronautical industry requires a technological maturity from new fabrication processes intended to become part of the productive process of planes. Additive manufacturing (AM) of parts made in metallic materials could offer several solutions in this industry (e.g. structural parts, fundamental parts in engines and turbines), envisioning of parts redesign or creation prioritizing weight reduction. However, a better understanding between microstructural and mechanical properties of AM parts need to be reached.Currently we are developing a project funded by the regular program of FAPESP, grant 2017/17697-5, where João Pedro Oliveira participates as a collaborator. This existing project aims to increase fracture toughness and strain capacity without affecting the standard mechanical strength of standard samples made by additive manufacturing (AM) using a selective laser melting (SLM) in a 18Ni300 maraging steel. In addition, Prof. João has a large experience conducting laser processing and welding of metallic materials, additive manufacturing using wire and arc additive manufacturing (WAAM), advanced characterization techniques for materials (SEM, TEM and DRX) and in-situ measurements using an X-ray diffraction from a synchrotron source.The strengthening of this partnership though the SPRINT project will increase the number of interaction topics between UNESP and FCT-UNL, bringing new knowledge in the academic formation of the students, developing processes with application in the aeronautical industry, and sharing results through short courses, conferences presentations and peer-reviewed publications.
