Preparation by Gravity Casting and hydrogen-storage properties of Mg–23.5 wt.%Ni–(5, 10 and 15 wt.%)La
Journal of Alloys and Compounds, 2008Co-Authors: Myoung Youp Song, Chang-dong Yim, Jong-soo Bae, Daniel R. Mumm, Seong-hyeon HongAbstract:Abstract Mg–23.5 wt.%Ni–(5, 10 and 15 wt.%)La alloys were prepared by Gravity Casting and their hydrogen-storage properties were examined after pulverizing. The Gravity cast Mg–23.5Ni–(5, 10 and 15)La alloys consist of α-Mg, Mg2Ni and Mg17La2 phases. The activated Mg–23.5Ni–10La alloy has the highest hydrogen-storage capacity of 4.96 wt.%H (from P–C–T curve) and the highest initial hydriding rate (hydrogen content 3.83 wt.%H at 10 min) with an initial hydrogen pressure in the channel of 11 bar H2 at 573 K. This is attributed to its containing the largest amount of the Mg17La2 phase, which is easily dissociable during the hydriding reaction.

effects of the Casting temperature on microstructure and mechanical properties of the squeeze cast al zn mg cu alloy
Journal of Alloys and Compounds, 2010Co-Authors: Cang Fan, Zhen Hua Chen, J H Chen, Ding ChenAbstract:Abstract The effects of the Casting temperatures on microstructure and mechanical properties of the squeeze-cast Al–Zn–Mg–Cu alloy have been investigated in this paper. The Casting temperature is selected as 660, 680, 700 and 720 °C, respectively. The Gravity Castings of the same alloy are also prepared at the above Casting temperatures for comparison. Both the grain size and the dendrite arm spacing (DAS) of the squeezing Casting increase with the increase of the Casting temperature, as like the Gravity Casting. However, the Casting temperature has a more obvious effect on the DAS of the Gravity Casting than that of the squeeze Casting. The optimum Casting temperatures for Gravity Casting and squeeze Casting are 720 and 680 °C, respectively. However, both the Gravity Castings and the squeeze Castings show the highest tensile elongation at the Casting temperature of 660 °C.
