Additive manufacturing (AM) plays a crucial role in the development of NiTi alloys, enabling creation complex and customized structures while optimizing properties for various biomedical industrial applications. The aim this paper was to investigate influence laser scanning speed on laser-assisted reactive sintering mixture No Ti powders. samples were sintered at two different beam speeds, 4 5 mm/s their morphological microstructural characteristics investigated. Scanning electron microscopy...
This work investigated the sintering of silicon carbide (SiC) with alumina (Al2O3) and yttria (Y2O3) additives by hot pressing. Mixtures SiC 1% 5% Al2O3 Y2O3 were used, pressed at 1800 °C 1850 °C, resulting in specimens that characterized terms density, microstructure, Vickers hardness fracture toughness. The addition oxide provided greater densification better mechanical properties. temperature proved to be most effective for due microstructure presented. analysis revealed a homogeneous...
In this study, nanometric powders of silicon carbide (SiC), micrometric alumina (Al₂O₃) and yttria (Y₂O₃), with specific characteristics provided by the manufacturers, were used to investigate compaction behavior resulting properties after sintering. The SiC has a purity over 99% particle size distribution d50 40 nm, while Al₂O₃ Y₂O₃ have purities 99.8% 99.995%, respectively. morphological evaluation was carried out using scanning electron microscopy (SEM), apparent density analysis...
PDF | O processo de manufatura aditiva (AM) é uma técnica que possibilita a produção integrada dispositivos, sendo aplicável em diversas áreas da indústria. Além disso, peças e componentes ligas NiTi com memória forma nesse apresenta opções processamento atraentes, desafiando as rotas convencionais fabricação, particularmente no diz respeito ao método Deposição por Energia Direcionada (DED). Contudo, características físicas químicas do pó empregado como matéria-prima exercem um impacto...
