Track A: Nano-laminated ternary transition metal carbides/nitrides (MAX phases) and borides (MAB phases), and their 2D counterparts (MXenes)

MAX and MAB phases are thermodynamically stable nanolaminates of early transition metals carbides, nitrides, and borides. They have unusual and unique properties, for example, MAX phases are hexagonal materials with an inherent nanolayered structure which provides a unique combination of metal-like and ceramic-like properties: machinability, good electrical and thermal conductivity, high thermal shock resistance, good oxidation resistance, stiffness at high temperature which opens a way to diverse potential applications. Recently, it was shown that it is possible selectively etch atomic metal layers out of the structure to separate each nanolaminate’s block of the transition metal compounds and form 2D solids. Despite their relatively short history, MXenes (the 2D phase after removing A layers from MAX phases) have attracted scientists attentions due to their attractive properties such as their excellent electronic conductivity and surface functionality and tunability. The Track A will focus on designing, processing, structure-property relationships, thermal, electrical, optoelectronic, solid lubrication, and mechanical properties, oxidation resistance, stability, and applications of these novel nanolaminates compounds in their 2D and 3D forms.


Track B: Ultra-high-temperature ceramics (UHTCs)

Ultra-high-temperature ceramics (UHTCs) are potential materials for use in extreme environments such as scramjet engine components, leading edges and thermal protection systems for hypersonic vehicles, etc. However, their thermal/chemical stability in extreme environments, the ability to be formed into complex shapes/sharp edges, thermal shock resistance, irradiation resistance, and damage tolerance are all critical challenges limiting near-term industrial applications of these materials. For such extreme environment applications, new advances in the understanding of structure-property relations and improved performance are needed. This Track B will focus on design, processing, structure-property relationships, thermal and mechanical properties, oxidation resistance, machining and joining, and stability of UHTCs both from fundamental and application-oriented perspectives.
