GROWTH AND MECHANICAL BEHAVIOR OF MIXED-DIMENSIONAL HETEROSTRUCTURES FOR HYPERSONIC APPLICATION

Abstract

Project aim to develop composite thin films with superior mechanical properties for hypersonic applications. We will achieve this goal by i) understanding the influence of two-dimensional (2D) layered materials, such as hexagonal boron nitride (hBN), on the growth of hard, refractory materials such as transition-metal carbide and nitrides (TMC/N) and ii) by carrying out a systematic investigation of the role of thin film composition, thickness, and microstructure on the mechanical properties. Our approach involves the synthesis of heteromodulus thin films with tunable architecture. As model materials systems, we choose elastically highly anisotropic hBN as the reinforcement in relatively isotropic and high-moduli TMCs and TMNs as the matrix.
