Microestrutura e propriedades mecânicas de vitrocerâmicos do sistema Li2O – CaO – SiO2
(Universidade Federal de São Carlos, 2013-03-12)
An interesting characteristic of the Li2O-CaO-SiO2 glass-forming system is the possibility of obtaining certain crystalline phases and morphologies that may lead to tough glass-ceramics. However, very few published works ...
Influência da microestrutura na resistência mecânica de ligas hipereutéticas Al-Si solidificadas direcionalmente
(Universidade Federal de São Carlos, 2017-01-18)
The present research work deals with directional solidification (DS) of Al-15wt.% and 18wt.% Si alloys and further characterization of the related microstructures. Emphasis is given on the eutectic growth being affected ...
Parâmetros térmicos de solidificação, microestrutura e resistência mecânica de ligas eutéticas Sn-0,7%Cu-(xNi)
(Universidade Federal de São Carlos, 2013-07-29)
Sn-Pb traditional solder alloys were overly utilize in electronic devices industry, since their properties and features use were adequate and well known. In the last years many restrictions and directives were and have ...
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, ...
