| Abstract Scope |
The increasing demand for materials with superior thermomechanical properties in extreme environments has garnered substantial interest in the development of super/ultra-hard materials for defense and energy applications. Through a systematic selection of material compositions and atomistic microstructural engineering, transition metal carbides, nitrides, and high entropy ceramics can be fabricated to challenge the hardness of c-BN and diamond. In addition to hardness, material attributes such as density, fracture toughness, thermal stability, cost efficiency, and manufacturing scalability should all be considered. This study presents the development of thin film and bulk material processing of material candidates for interfacial-directed and macroscopic spinodal decomposition. The utilization of physical vapor deposition techniques and field-assisted sintering technology for thin film and bulk ceramic processing respectively allows for tailoring of morphology, interfacial coherency, grain size, residual stress, and density. Therefore, process-structure-property-performance relationships are required to advance next generation hard ceramic material systems and processing methodologies. |
