Desenvolvimento de vitrocerâmicos transparentes resistentes ao impacto
(Universidade Federal de São Carlos, 2021-11-11)
Transparent glass-ceramics (GCs) can replace glasses traditionally used as ballistic windows and electronic displays due to their better mechanical properties. This improvement is obtained by the crystallization of phases ...
Computational modeling of rubber multiaxial pressing applied to ceramic materials
(Universidade Federal de São Carlos, 2021-04-07)
Uniaxial and isostatic powder pressing are well known processes. However, disadvantages such as the production of heterogeneous parts or low productivity, respectively, are intrinsic drawbacks. Rubber Multiaxial Pressing ...
Juntas de aço inoxidável super duplex UNS S32760 soldadas por fricção e mistura mecânica (FSW): microestrutura e comportamento de corrosão eletroquímica
(Universidade Federal de São Carlos, 2022-04-29)
In this study, the corrosion resistance of the face and root surface of an AISD UNS S32760 friction stir welded (FSW) joint using optimized parameters was investigated. Microstructural changes were evaluated by MO, SEM and ...
Reciclagem de embalagens flexíveis multicamadas
(Universidade Federal de São Carlos, 2022-04-29)
Packaging industry is facing an important paradox in flexible plastic packaging for fresh food. While, food waste is avoided using multilayer and multi-material structures with barrier properties, that increase shelf life ...
Design, processing, and characterization of high strength precipitation-hardened CrCoNiAlTi high entropy alloys
(Universidade Federal de São Carlos, 2023-03-22)
High Entropy Alloys (HEAs) have been attracting considerable interest in literature. While early studies focused on producing single-phase HEAs, more recent investigations have expanded to multi-phase compositions to take ...
