| Research Abstract |
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.
