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 ...
Overview of Al-Si alloys for additive manufacturing and prospects
(Universidade Federal de São CarlosUFSCarCâmpus São CarlosEngenharia de Materiais - EMa, 2021-11-18)
Additive manufacturing (AM) has emerged in recent years for enabling the generation of parts with highly complex geometries. Due to the nature of the AM process, which causes alloys to experience a complex thermal history ...
Effect of alloying elements in melt spun Mg-alloys for hydrogen storage
(Universidade Federal de São Carlos, 2016-07-25)
In this paper we report the effect of alloying elements on hydrogen storage properties of melt-spun Mg-based alloys. The base alloys Mg90Si10, Mg90Cu10, Mg65Cu35 (at%) were studied. We also investigated the effect of rare ...
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 ...
Effect of Mg Alloying Addition on Dissolution Behavior of Oxide Films in Al-Si-Mg Alloys
(IOP Science, 2007-05)
Cyclic polarization measurements were carried out for Al-10%Si- X%Mg (X: 3%, 6% and 9.5%) alloys in borate solutions with and without additions of 50 mM NaCl. The voltammetric response exhibited some features of oxide film ...
Processamento e caracterização microestrutural e mecânica de uma liga de alumínio da série 6xxx extrudada
(Universidade Estadual Paulista (Unesp), 2022-08-08)
O uso de ligas de alumínio está em expansão em diversos nichos de mercado, oferecendo uma alternativa leve ao aço. A escolha da liga é um dos principais fatores que corroboram com a resistência, possibilitando aumento da ...
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 ...
