| 摘 要： | 分别研究了具有两种界面结构的Ｉｎ和Ｐｂ纳米镶嵌颗粒（Ａｌ基体）的熔化行为，发现与Ａｌ基体具有附生取向关系的Ｉｎ和Ｐｂ纳米颗粒的熔点升高，而与Ａｌ基体随机取向的Ｉｎ和Ｐｂ纳米颗粒的熔点则降低，说明界面结构决定了纳米颗粒熔点的升降。

| Abstract: | Melting behaviors of In and Pb nanoparticles embedded in Al matrices were studied by using DSC and in situ TEM observations. It was found that the epitaxially oriented (with the Al matrix) In and Pb nanoparticles could be superheated, while the randomly oriented in and Pb nanoparticles may melt below their equilibrium melting points. Authors suggest that the melting point of the embeded nanoparticles can be either enhanceded or depressed, depending on the nature of the interfaces. |
