有效的纳米粒子掺入和分散一直是金属基纳米复合材料固化加工的长期挑战。这项研究报告了一种熔盐辅助方法，该方法能够将 TIC 纳米颗粒有效地掺入熔融铝中，以生产具有致密且分散良好的纳米颗粒的母纳米复合材料。通过将这种母纳米复合材料稀释到纯铝中，可以很容易地制造出具有不同纳米颗粒浓度的 Al-TiC 纳米复合材料。纳米复合材料的显微硬度显着提高。这种简单且可扩展的制造工艺为金属基纳米复合材料的大规模凝固加工铺平了一条实用的道路。
Effective nanoparticle incorporation and dispersion have been long-standing challenges for solidification processing of metal matrix nanocomposites. This study reports a molten salt assisted method that enables an effective incorporation of TIC nanoparticles into molten aluminum to produce master nanocomposites with dense and well-dispersed nanoparticles. By dilution of this master nanocomposites into pure aluminum, Al-TiC nanocomposites with various concentrations of nanoparticles were readily fabricated. Microhardness of the nanocomposites was dramatically enhanced. This simple and scalable manufacturing process paves a practical way for mass solidification processing of metal matrix nanocomposites.
