| 1 | Microstructure and mechanical properties of hypereutectic Al-Si alloy modified with Cu-P显示文摘The microstructure and mechanical properties of Al-14.6Si castings modified by Cu-P master alloy under different conditions were studied with optical microscope(OM) and mechanical testing and simulation(MTS).The results indicate that the Cu-P master alloy possesses not only obvious modification effect,but also longevity effect with more than 8 h on the hypereutectic Al-Si alloy.It is shown from thermal calculation,scanning electron microscope(SEM),and energy dispersive analysis of X-rays(EDAX) that the modification mechanism of Cu-P on primary silicon in the castings is heterogeneous nucleation around AlP particles.The Cu-P master alloy has no or little modifying effect on eutectic silicon,even though it has obvious modification on primary silicon in the castings.This may be because of the fast transformation of eutectic silicon at a very narrow temperature,which will notably weaken the role of AlP particles as heterogeneous nuclei for eutectic silicon. | ZHANG Henghua DUAN Haili SHAO Guangjie XU Luoping | 2008 | Rare Metals2008，27，1： | 35 |
| 2 | Modification mechanism of cerium on the Al-18Si alloy显示文摘在不同扔的状态下面的高级低共熔体的 Al-Si 合金上的稀土元素铈(Ce ) 的效果被光显微镜和量的图象分析学习了。尺寸和在铸造物的主要的硅的数量随 melt 的增加的 Ce 的增加减少,这被发现。好 facetted 形状的从分叉的形状的同时主要的硅变化。尽管在铸造物的最容易溶解的硅上的修正也随 melt 的增加的 Ce 的增加改善,离开主要的硅的最容易溶解的硅上的修正的效果在到主要的硅的最容易溶解的硅结束上是比那更明显的。修正机制借助于扫描详细被分析电子显微镜与精力装备了 X 光检查和热力学分析的散分析,它在反应和反应平衡的标准吉布斯精力在变化上包括了分析。 | ZHANG Henghua DUAN Haili SHAO Guangjie XU Luoping YIN Junlin YAN Biao | 2006 | Rare Metals2006，25，1： | 23 |
