Abstract:
In 2021 was completed the upgrade of the European Synchrotron Radiation Facility ESRF – EBS (Extremely Brilliant Source), becoming the first new generation of high-energy synchrotron, increasing brilliance and coherence of X-ray beams by a factor of 100 compared to present-day light sources. The highlights of the research activities in powder metallurgy made in these 2 years would be presented: the measurement of stress relief given by heat treatment on the residual stresses of an additive manufactured AISI 316L stainless steel arch structure (part of EU-funded EASI-STRESS project); a synchrotron μ-tomographic morphological description of additively manufactured open porous structures made by Laser-based Powder Bed Fusion (L-PBF), to characterize attached spherical particles on the surface of functional structures; a study about the solidification of a new Al-4Mn-3Ni-2Cu-1Zr alloy, designed for L-PBF, developing a new strategy for alloy design in high-strength aluminum alloys for powder metallurgy.
