Abstract
As one novel reinforcement used in magnesium composite, nano-layered flaky ternary MAX particle exhibits interesting anisotropic ceramic and metal properties. In order to accurately simulate the mechanical properties and damage behavior of MAX particle reinforced magnesium composite, we developed one finite element (FE) model based on 2D and 3D microstructural observations of 10 vol.% Ti2AlC-AZ91D composite. To improve the accuracy, matrix ductile damage, particle internal delamination deformation behaviors, and particle-matrix interfacial behaviors were respectively introduced into this model. The visual deformation processes of crack generation and propagation were carefully presented and discussed. The effects of interfacial strength and particle orientation on material properties were systematically investigated.
