Abstract Scope |
Nanoparticles have been used to facilitate processing and strengthen Al alloys in solidification processing. However, the potential reactivity of Si and its compounds (e.g., β-Mg2Si) with TiC nanoparticles at high temperatures makes solidification processing challenging for Al-Mg-Si containing TiC nanoparticles. Given the broad applications of Al-Mg-Si alloys, how TiC nanoparticles affect its solidification processing and resultant properties is of significance. Here, we systematically studied the modified phase and composition by TiC nanoparticles in as-cast and heat-treated Al-Mg-Si alloys. The interaction between TiC and Si-rich phases like β-Mg2Si has been analyzed. The mechanical performance, including hardness and tensile properties, and fractography have been studied and correlated with the TiC-induced nano-treating effects. This study provides useful insights to develop high-performance Al-Mg-Si alloys with ceramic nanoparticles. |
