Abstract Scope |
A synergetic integration of diverse energy technologies is envisioned to meet the continuously increasing energy demands in the power generation and transportation sectors while simultaneously addressing CO2 reduction targets. High temperature corrosion will be a critical life-limiting degradation mechanism that must be addressed early on in alloy development procedures. However, the expected component lifetimes are too long for experimental verification and alloy development at reasonable costs is only possible through accurate and validated computational methodologies. This talk will discuss the applicability of existing computational approaches to predict corrosion induced degradation and the microstructural evolution in high temperature alloys as a function of alloy/coating composition, environment (air, steam, supercritical CO2, molten halide salts), time and temperature. Long-term experimental data combined with detailed microstructural characterization will be employed to validate the modeling results. An outlook on the aspirations and challenges in developing advanced modeling tools in the future will be presented. |
