Abstract
High temperature material solutions for future power generation applications require longer component lifetimes at higher temperatures to improve durability and efficiency. From a research and development point of view, the lifetimes are too long for experimental verification. Thus, accurate lifetime models are needed. Examples are provided where modeling is being applied to lifetime prediction of thin-walled NiCr wrought alloy components. Specific laboratory experiments have been conducted for alloy X at 900°-950°C in dry air and air with water vapor with cycle times from 1 to 500 h. Along with microstructure characterization, comparisons are made between experiment and model predictions. The eventual goal is to predict both oxidation and mechanical behavior.
