effect of Ce on microstructure mechanical properties and corrosion behavior of high pressure die cast mg 4al based alloy
Journal of Alloys and Compounds, 2011Co-Authors: Jinghuai Zhang, Zhe Leng, Milin Zhang, Jian Meng, Ruizhi WuAbstract:Mg-4Al-xCe-0.3Mn (x=0, 1, 2, 4 and 6 wt.%) alloys were prepared by high-pressure die-casting. The microstructures, mechanical properties and corrosion behavior were investigated. The cross-section of test bar is divided into the fine skin region and the relatively coarse interior region by a narrow band. The dendritic arm spacing is greatly reduCed and the secondary phases Al(11)Ce(3) and (Al, Mg)(2)Ce with the former being the dominant one substitute the Mg(17)Al(12) phase with addition of Ce. When Ce Content reaches 4 wt.%, the alloy exhibits an optimal cost performanCe ratio. The improved mechanical properties maintained up to 200 degrees C are mainly related to the fine grain size and the main strengthening phase Al(11)Ce(3), which is present in a high volume fraction, and possesses fine acicular morphology and relatively good thermal stability. The improved corrosion resistanCe is attributed to the microstructure modification of the alloys and the corrosion product films. (C) 2010 Elsevier B.V. All rights reserved.

microstructure mechanical and corrosion properties of novel mg sn Ce alloys produCed by high pressure die casting
Materials Science and Engineering: C, 2019Co-Authors: Selma Ozarslan, Huseyin Sevik, Idris SorarAbstract:Abstract The aim of this study was to investigate the effect of adding 1, 2 and 4% wt of Cerium on the microstructure, mechanical and corrosion properties of high pressure die casting (HPDC) Mg-4Sn alloys. Microstructure analyses of the alloys were carried out using X-Ray Diffraction (XRD) and Scanning Electron microscopy (SEM). The corrosion behaviors were determined with the potentiodynamic polarization and immersion tests in Hanks BalanCed Salt Solution (HBSS), which is used as the artificial body fluid. The microstructural results showed that the addition of Ce to the main alloy creates new intermetallic phases (Ce5Sn4 and MgSnCe). In addition, Ce addition provided effectively the grain refinement of the alloys. While the hardness and yield strength of the Mg-4Sn alloy enhanCed continuously with increasing Ce Content, the tensile strength and elongation reached up to 2% wt. The corrosion resistanCe of the main alloy was improved by the addition of 1% wt of Ce. However, the Ce Content, which is more than 1% wt decreased corrosion resistanCe.
