Fabrication and performance of 3D co-continuous magnesium composites rein-forced with Ti2AlNx MAX phase
文献摘要：
Magnesium composites reinforced by N-deficient Ti2AlN MAX phase were first fabricated by non-pressure infiltration of Mg into three-dimensional (3D) co-continuous porous Ti2AlNx (x = 0.9, 1.0) preforms. The relationship between their mechanical properties and micro-structure is discussed with the assessment of 2D and 3D characterization. X-ray diffraction (XRD) and scanning electron microscopy detected no impurities. The 3D reconstruction shows that the uniformly distributed pores in Ti2AlNx preforms are interconnected, which act as infiltra-tion tunnels for the melt Mg. The compressive yield strength and microhardness of Ti2AlN0.9/Mg are 353 MPa and 1.12 GPa, respectively, which are 8.55％ and 6.67％ lower than those of Ti2AlN/Mg, respectively. The typical delamination and kink band occurred in Ti2AlNx under compressive and Vickers hardness (VH) tests. Owing to the continuous skeleton structure and strong interfacial bonding strength, the crack ini-tiated in Ti2AlNx was blocked by the plastic Mg matrix. This suggests the possibility of regulating the mechanical performance of Ti2AlN/Mg composites by controlling the N vacancy and the hierarchical structure of Ti2AlN skeleton.
