Influência da nióbia no óxido de alumínio eletrofundido para aplicações abrasivas
(Universidade Federal de São Carlos, 2021-07-29)
Abrasives are materials that have as main characteristics their cutting and
grinding power. In its most common crystalline form, aluminum oxide, due to its
high melting point, high hardness and mechanical resistance, ...
Estabilidade microestrutural da liga Cu-0,8Cr-0,07Zr após extrusão em canal angular em temperatura criogênica
(Universidade Federal de São Carlos, 2021-12-20)
Severe Plastic Deformation (SPD) are well established routes with regard to the
intense microstructural refining of metals and alloys up to the submicrometer (<
1 μm) and/or nanometer (< 100 nm) scales. Lowering the ...
Evolução microestrutural e propriedades mecânicas decorrentes da solidificação das ligas Al-11%Si-xCu
(Universidade Federal de São Carlos, 2018-11-21)
Al-Si-Cu ternary alloys are highly used and recommended to produce joints of aluminum alloys using brazing process. Dissimilar joints between these alloys and stainless steels, carbon steels and low alloy steels can also ...
Desenvolvimento de cerâmicas refratárias engenheiradas densas e porosas
(Universidade Federal de São Carlos, 2019-09-04)
High temperature processes are of great importance as they are widely applied in the manufacture of commodities, consumer goods and advanced materials. For these processes to be possible, the thermal environment in which ...

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 ...
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 ...
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 ...
