Abstract: Cover Photograph: The complex phase equilibria in the tantalum carbide system allows for the development of varied microstructures with associated interfacial structures between the phases. The top-left image is a backscattered scanning electron image of a multiphase TaC, ζ-Ta4C3-x, and Ta2C microstructure. The top-right image is an atom probe reconstruction of the zeta phase laths (green) in a TaC matrix (purple). The blue regions in this atom probe reconstruction represent complex Ta-C ion combinations that were field evaporated. The bottom left image is a focus ion beam-serial sliced, reconstructed image of a singular TaC grain (blue) with two zeta laths (red) encased within the grain. Finally, the bottom right image is an HRTEM micrograph of an interface between the ζ-Ta4C3-x and Ta2C phases highlighting the stacking fault shear that creates each phase from the other.
