Dynamic Interplay between Phase Transformation and Material Degradation in Extreme Environments

The complex and often interconnected processes that occur when materials are subjected to multi-extreme conditions such as high temperatures, mechanical stresses, high pressures, radiation, corrosion, and other harsh environments are difficult to understand and predict based on the current knowledge base. This interplay can have significant implications for the performance, reliability, and durability of materials in various applications, including aerospace, nuclear, energy, and defense. Phase transformation refers to the change in the structure or composition of a material, often accompanied by changes in its physical, mechanical, and chemical properties. Material degradation, on the other hand, refers to the gradual deterioration of a material’s properties due to various mechanisms, such as mechanical wear, corrosion, radiation damage, thermal cycling, and fatigue. In extreme environments, phase transformation and material degradation can interact in complex ways, often influencing each other’s behavior. For example, the formation of new phases during phase transformation can affect material degradation by altering the material’s microstructure, grain boundaries, and defect concentrations, which can impact its mechanical and chemical properties. Similarly, material degradation processes can influence phase transformation by changing the availability of certain elements or altering the local conditions, such as temperature, pressure, and chemical environment, which can affect the kinetics and thermodynamics of phase transformations. Understanding the dynamic interplay between phase transformation and material degradation in extreme environments is crucial for designing materials with enhanced performance and durability. In this project, the student will study the changes in corrosion resistance of a metallic system undergoing thermo-mechanically induced phase transformation.
