Dendritic Spacing and Macrosegregation Affecting Microhardness of an Al-Si-Mg Alloy Solidified Under Unsteady State Conditions
(Univ Fed Sao Carlos, Dept Engenharia Materials, 2019-01-01)
The prediction of microstructure morphology is fundamental for the manufacture of metallic components, since the expected levels of mechanical properties will be associated with the final aspects of the microstructure. In ...
Evolução microestrutural e propriedades mecânicas das ligas Al-10%Si-0,45%Mg e Al-10%Si-1,0%Mg
(Universidade Federal de São CarlosUFSCarPrograma de Pós-Graduação em Ciência dos Materiais - PPGCM-SoCâmpus São Carlos, 2021-07-28)
Al-Si alloys with high silicon (Si) content are widely used in aerospace, automotive, microelectronics, among others. In this context, the Al-10 wt.% Si alloys with the addition of Magnesium (Mg) are alternatives that ...
Significant hardness enhancement in an Al–Cu–Mg alloy with high Cu:Mg ratio by microalloying with Si and Ge
(Elsevier, 2018-12)
The evolution of hardness in an Al-Cu-Mg based alloy with high Cu:Mg ratio (= 2, at. %) microalloyed with Si and Ge was studied during artificial ageing treatment performed at 190 °C. The results were compared to those ...
Análise da influência do teor de magnésio sobre os parâmetros microestruturais de ligas Al-7Si-(Mg) solidificadas em regime transiente e sua correlação com propriedades mecânicas
(Universidade Federal de São Paulo (UNIFESP), 2019-02-15)
The mechanical behavior of cast metal products depends directly on the mechanical properties resulting from the microstructural arrangement. Establishing correlations between these microstructural arrangements and the ...
Selective liquid-phase hydrogenation of furfural to furfuryl alcohol over Cu-based catalysts
(Elsevier, 2013-02)
In this work, the liquid-phase furfural hydrogenation over different Cu-based catalysts was studied. The catalysts were prepared by incipient wetness impregnation (Cu/SiO2-I), precipitation?deposition(Cu/SiO2-PD) and ...
