Probing Structure and Composition of Nickel/Titanium Carbide Hybrid Interfaces at the Atomic Scale (Preprint)

Abstract

The transition in structure and composition across the titanium carbide/nickel hybrid interface has been determined at near atomic resolution by coupling high-resolution transmission electron microscopy with three-dimensional atom probe tomography. The titanium carbide phase adopts a rocksalt-type structure, is highly non-stoichiometric with a composition of (Ti+Ni)2C, exhibits an orientation relationship with the nickel matrix with a structurally well-defined semi-coherent interface, and a compositionally distinct interfacial layer (~ 2 nm), that is marginally enriched in titanium and nickel and depleted in carbon.
