| 1 | Mechanical properties of squeeze-cast Al-7Si-0.3Mg alloys with Sc-modified Fe-rich intermetallic compounds显示文摘Iron (Fe) has a low solid solubility in aluminum(Al), and it usually forms Fe-rich intermetallic compounds.Scandium (Sc) is an element that can act as a grain refiner,modify the eutectic silicon and change the morphology of Fe-rich intermetallic compounds at the same time. The present work was conducted to study the effect of Sc on the mechanical properties of Al-7Si-0.3Mg. The alloy was prepared by squeeze casting at two levels of Fe (0.2 and 0.4 wt%) and three levels of Sc (0 wt%, 0.2 wt% and 0.4 wt%). Sc is found to increase the mechanical properties of the alloy, including its hardness, yield strength and ultimate tensile strength. At 0.2 wt%Fe, adding Sc increases the strength while maintaining good elongation.At 0.4 wt%Fe, adding Sc increases the strength but decreases the elongation slightly. The distributions and morphologies of intermetallic compounds and eutectic silicon affect the elongation. Both Fe-rich intermetallic compounds and Sc-rich intermetallic compounds act as crack initiation sites. The 0.2 wt% Fe+0.2 wt% Sc alloy has the lowest amount of these intermetallic compounds,and eutectic silicon is small and fibrous. So, it has the highest elongation. | Kittisak Chanyathunyaroj Ussadawut Patakham Sindo Kou Chaowalit Limmaneevichitr | 2018 | Rare Metals2018，37，9： | 8 |
| 2 | Effect of Sc on Precipitation Hardening of AlSi6Mg Alloy显示文摘AISi6Mg 变硬的降水上的 Sc 的效果是 studied.Zr 以前被报导它增加了 Sc 的有效性在做在 Zr 因此也是的许多区域的铝在这研究和 Sc 使用了。Sc 和 Zr 增加的不同层次在在永久模子扔前被加到 AISi6Mg。样品是降水在为张力的力量和坚硬测试前在不同老化温度并且在各种各样的老化时间变硬。进 AI6SiMg 的 Sc 增加能改变它的反应变老变硬,这被发现。有 Zr 的 Sc 和 Sc 的增加为两变老的温度增加了收益力量和坚硬。另外, Sc 被发现修改最容易溶解的 Si 获得含纤维的形态学。最容易溶解的硅修正上的 Sc 的这效果以前从来没被报导过。 | Wattanachai Prukkanon Satit Chanpum Chaowalit Limmaneevichitr | 2008 | Journal of Materials Science & Technology2008，24，1： | 4 |
| 3 | Effect of Process Parameters on Morphology and Grain Refinement Efficiency of TiAl_3 and TiB_2 in Alumimum Casting显示文摘这篇论文在生产 Al-5Ti-1B 谷物论述不同进程参数的效果更精制, i.e.various 序列和反应时间,在铝铸造物的谷物精炼效率上。不同进程参数在谷物导致了不同形态学和 TiAl3 和 TiB2 的尺寸分发,这被发现更精制。实验被把 KBF4 和 K2TiFe 加到熔融的铝执行。融化的温度在一个电的抵抗炉子在 800 ° C 被控制。KBF4 和 K2TiF6 增加的三个不同序列被使用,即,在 K2TiF6 前的增加的 KBF4,在 KBF4 前增加 K2TiF4 并且在增加熔融的铝前混合 KBF4 和 K2TiF6。在 1 min, 30 min 和 60 min 的三不同成立时间被使用。结果证明形态学和尺寸分发的重要差别都没被改变三个不同序列发现。而,不同成立时间在形态学和尺寸分发提供了主要差别,它从在比 30 min 长导致更大的粒子尺寸和反应时间是的 TiAl3 和 TiB2.If 的尺寸分发的更宽的范围的粒子之间的散开和凝块是技术上能预期的, TiAl3 和 TiB2 的形态学变得太大。如果反应时间是太短的,在到形式的 TiAl3 和 TiB2 之间的更少的反应将被获得。为谷物精炼效率,它在与 min 导致了最好的谷物精炼效率的 30 的一成立时间增加熔融的铝前被发现那混合 KBF4 和 K2TiF6, | Prapas Kunnam Chaowalit Limmaneevichitr | 2008 | Journal of Materials Science & Technology2008，24，1： | 3 |
