Size effects affecting the phase diagrams of metals and alloys

从实验和理论两方面研究了尺寸对金属和合金相图的影响。研究表明，纯金属纳米颗粒的相稳定性可以通过构成底物元素在纯纳米颗粒中的溶解度来控制。结果表明，共晶温度随合金纳米颗粒半径的反比成比例地降低，且线性关系的斜率总是比纯金属的斜率变陡。

The size effects affecting the phase diagrams of metals and alloys, have been studied both experimentally and theoretically. It is made clear that the phase stability of a pure metal nanoparticle can be controlled by the solubility of a substrate-constituting element in the pure nanoparticle. It is also revealed that the eutectic temperature decreases in proportion with the inverse radius of an alloy nanoparticle and always the slope of the linear relationship becomes steep as compared to the slope in pure metals.
