制备了In纳米颗粒镶嵌在铝基非晶基质中的复合材料。随着In含量的增加，In纳米颗粒的平均尺寸增大。研究了包埋纳米粒子的熔融行为，结果表明，纳米粒子的熔融温度受到抑制，且粒子越小，熔融温度越低。通过将差示扫描量热曲线与粒度分布曲线进行比较，证实了这一点。利用热力学模型讨论了纳米粒子的熔融行为与尺寸的关系。
The composites of In nanoparticles embedded in Al-based amorphous matrix were synthesized. As the content of In increases, the average size of In nanoparticles increases. The melting behaviors of embedded In nanoparticles were investigated, indicating that the melting temperature is suppressed, and the smaller the size is, the lower the melting temperature is. It is confirmed by comparing the differential scanning calorimetry curves with those of the size distribution. The size dependent melting behaviors of nanoparticles were discussed with the thermodynamic model.
