(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 ...
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 ...
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 ...
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 ...
