Interformational Exfoliation of Ti3Al2 Induced by Cu


Article Preview

An interformational exfoliation behavior of the layered Ti3AlC2 induced by copper was firstly investigated via a “Cu-Ti3AlC2-Cu” sandwich sample infiltration-sintered at 1100oC to 1200oC. It was found that the molten Cu accelerates Ti3AlC2 to decompose, induces the interformational exfoliation to generate, and consequently forming a sub-micro-layered structure making up of TiC0.67 layers and Cu-Al alloy layers within a Ti3AlC2 grain. This interformational exfoliation behavior can be attributed to a topotactic mechanism due to the outward diffusion of Al the entering of Cu.
