Conde, F. F.; Avila, J. A. [UNESP]; Oliveira, J. P.; Schell, N.; Oliveira, M. F.; Escobar, J. D.Made available in DSpace on 2022-04-28T19:41:08Z (GMT). No. of bitstreams: 0 Previous issue date: 2021-10-01; Conselho Nacional de Desenvolvimento Científico e Tecnológico (CNPq); Nuclear Fuel Cycle and Supply Chain; During laser-based powder bed fusion, the non-equilibrium solidification conditions promote local elemental segregation, leading to a characteristic microstructure composed of cellular walls. These...
