Análise da microestrutura, parâmetros térmicos e de propriedades mecânicas na solidificação de ligas com alto teor de cobre Al-(x)%Cu-7%Si
(Universidade Federal de São Carlos, 2019-02-26)
Ternary Al-15%Cu-7%Si and Al-22%Cu-7%Si alloys specimens were obtained by transient directional solidification (DS). This technique is able to provide a very large range of cooling rates and microstructures to be correlated ...
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 ...
Análise da microestrutura, parâmetros térmicos e de propriedades mecânicas na solidificação direcional de ligas Al-Mg-Fe
(Universidade Federal de São Carlos, 2017-01-18)
Al-Mg-Fe alloys are appointed as favorable ones in respect of the costs involved and all the required properties for successful vessel service. However, experimental inter-relations of solidification thermal parameters, ...
Biomimetism of Brazil nutshell (Bertholletia excelsa)
(Universidade Federal de São Carlos, 2020-08-07)
For thousands of years, nature has accumulated countless possibilities for optimized
solutions to engineering problems using limited raw material, room temperature,
aqueous solutions, solar energy and renewable resources. ...
Influence of Bobbin Tool Friction Stir Welding (BT-FSW) variants on the microstructure and properties of AA2060 and AA2196 aluminum alloys
(Universidade Federal de São Carlos, 2020-06-18)
In order to reduce total costs in aircrafts production, operation and maintenance, materials and processing techniques have been continuously further optimized. In this scenario, aluminum-lithium alloys have been studied ...
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 ...
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 ...
