Estudo de Ligas Fe-Nb-B Nanocristalinas Eutéticas Ultrafinas e Laser Cladding de Pós Atomizados
(Universidade Federal de São Carlos, 2020-05-20)
Fe-Nb-B alloys have gained much attention in recent years because of the possibility to obtain different constituents in nanostructured composites, amorphous and ultrafine eutectics (scale of 100 nm to 1 μm) alloys depending ...
Caracterização de interfaces para aplicações em ultra-alto vácuo através de brasagem dissimilar entre nitreto de boro hexagonal (h-BN), a liga de adição Ag-Cu-Ti e o Mo metálico
(Universidade Federal de São Carlos, 2020-08-14)
This work aimed to evaluate the vacuum brazing of h-BN/Mo systems for fabrication of the BPM (Beam Position Monitor) in synchrotron radiation beam. The h-BN has low surface wettability and is difficult to weld. The materials ...
