Vitrocerâmica altamente bioativa, de boa resistência mecânica e baixo módulo elástico
(Universidade Federal de São Carlos, 2019-09-03)
Bioactive glass and glass-ceramics have the property of binding directly to living tissue. However, from mechanical performance, these materials have some disadvantages such as low fracture resistance. Some properties ...
Evolução microestrutural e propriedades mecânicas das ligas Al-10%Si-0,45%Mg e Al-10%Si-1,0%Mg
(Universidade Federal de São Carlos, 2021-07-28)
Al-Si alloys with high silicon (Si) content are widely used in aerospace, automotive, microelectronics, among others. In this context, the Al-10 wt.% Si alloys with the addition of Magnesium (Mg) are alternatives that ...
Comportamento mecânico sob fadiga de compósitos de polipropileno com reforço híbrido de fibras e microesferas ocas de vidro
(Universidade Federal de São Carlos, 2018-02-05)
Short glass fiber (GF) reinforced polypropylene (PP) composites can be hybridized with hollow glass beads (HGB) in order to minimize the adverse effects arising from the preferential fiber orientation in injection molded ...
O efeito dos tratamentos térmicos na microestrutura e nas propriedades mecânicas de rodas automotivas fundidas a baixa pressão na liga A356
(Universidade Federal de São Carlos, 2019-12-13)
The low-pressure die casting process to produce automotive aluminum alloy wheels is well known, and, in the last decades, has been consolidated as the most common way to produce light automotive wheels in large scale. The ...
Levantamento de correlações de solidificação da liga A356 para aplicação em simulação computacional e projetos de rodas automotivas
(Universidade Federal de São Carlos, 2024-02-27)
Wheels are safety items with high structural demand. AlSi alloys stand out due to their good ratio between density and strength. The use of A356 alloy processed by Low-Pressure Die Casting (LPDC) and T6 heat treatment ...
Vitrocerâmicas de silicato de lítio com gradientes microestruturais - simulações e experimentos
(Universidade Federal de São Carlos, 2022-08-08)
The microstructure of glass-ceramics (GCs) depends on their chemical
composition and thermal history, from the cooling of the precursor glass to the
heat treatments. In glass production, the cooling rate on the surface ...
Microestrutura e propriedades mecânicas da liga Al7SiMg contaminada com 2,8%Fe e processada por fusão seletiva a laser
(Universidade Federal de São Carlos, 2022-06-28)
The solidification kinetics imposed by Selective Laser Melting (SLM) leads the microstructure of the manufactured metallic components to present intrinsic characteristics such as: microstructural and phase refinement, ...
Avaliação do efeito de ordenamento atômico nas propriedades da liga de elemento multiprincipal Cr33Co33Ni33
(Universidade Federal de São Carlos, 2024-02-23)
Previously, it was believed that Multi-Principal Element Alloys (MPEAs) were constituted as a random solid solution. However, recent studies have analyzed the contribution of the mixing enthalpy to the Gibbs free energy ...
