Caracterização do efeito da rugosidade em filmes finos de TiNb sobre o aço 316L para aplicação na biomedicina
(Universidade Federal de São Carlos, 2017-03-10)
With the increase in life expectancy, there has been a raise in the use of prostheses due to the need to replace parts of the human body. To avoid tissue rejection, metal alloys from implants should be biocompatible. The ...
Soldagem por fricção e mistura da liga de alumínio AA2198-T851 em chapas de diferentes espessuras
(Universidade Federal de São Carlos, 2012-12-11)
Friction Stir Welding (FSW) process, conceived in 1991, has been the target of research in the last decades due to the excellent properties presented by its welded joints, favored by the fact of occurrence in the solid ...
Avaliação do comportamento reológico, térmico e mecânico de misturas de PBAT com elevados teores de lignina
(Universidade Federal de São Carlos, 2019-12-17)
The massive accumulation of plastic waste and its environmental impact is in great evidence today. Each year, more than 8 million tons end up in the oceans, so research indicates that there will be more plastics than fishs ...
Análise sistêmica das massas de tamponamento para altos-fornos
(Universidade Federal de São Carlos, 2010-05-05)
The increase in the world steel production mainly observed in the last decade demanded a significant growth in the hot metal production through the blast furnace process. A key point in blast furnaces operation is related ...
Desenvolvimento de compósitos biodegradáveis a partir de amido termoplástico e fibras vegetais
(Universidade Federal de São Carlos, 2011-09-16)
This project had as main objectives to obtain and to develop new and biodegradable composites from renewable sources using a thermoplastic starch (TPS) matrix reinforced with different amounts of natural fibers, acuri, ...
Previsão de viscosidade e temperatura liquidus de vidros óxidos via redes neurais artificiais
(Universidade Federal de São Carlos, 2020-04-30)
The number of glass compositions that have already been studied (~10^5) is many times smaller than the potential glass compositions (~10^52). The traditional method “cook and look” all of the potential compositions to ...
Perspectivas e estratégias para melhoria da educação em engenharia de materiais brasileira
(Universidade Federal de São Carlos, 2020-09-10)
Engineering Education (EE) has greatly expanded in Brazil over the last decades and, over the last few years, some criticisms to the Brazilian EE started to gain traction. A reform to the national guidelines for engineering ...
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 ...
Desenvolvimento de manta flexível altamente bioativa
(Universidade Federal de São Carlos, 2011-07-29)
Recently, intensive studies have been conducted with biomaterials aiming their application as synthetic grafts for reparation and maintenance of bones, teeth and cartilage tissues that have been damaged or lost due to ...
