A356 alloys with novel core–shell heterostructures were fabricated by the addition of Ce and TiCN nanoparticles, and the A356-1.5 vol pct TiCN-0.5 wt pct Ce alloy had excellent mechanical properties. The core–shell heterostructure contained an enriched Fe core so as to reduce the harmful effects of Fe impurity on the mechanical properties and provided significant load-bearing strengthening effects. Furthermore, the crack propagation from the core to the α-Al matrix was strongly hindered by the shell and hence improved the ductility.

AST-A356-1.5 Vol Pct TiCN-0.5 Wt Pct Ce复合材料的核-壳异质结构及其对力学性能的影响

通过添加Ce和TiCN纳米粒子制造了具有新颖核-壳异质结构的A356合金，并且A356-1.5 vol pct TiCN-0.5 wt％Ce Ce合金具有出色的机械性能。核-壳异质结构含有丰富的铁核，从而减少了铁杂质对机械性能的有害影响，并提供了显着的强化载荷作用。此外，壳强烈地阻止了从核到α- Al基体的裂纹扩展，从而改善了延展性。
