Major objective of the proposed project is to develop better understanding of the inter-relationship of processing steps, grain boundary character distribution (GBCD), and creep behavior of high-temperature structural alloys. The main goals of this study are ; (1) to process microstructures with a distribution of random and special grain boundaries; (2) to measure grain boundary character distribution (GBCD); (3) to perform creep testing of varied microstructures; (4) to model the effects of grain size, grain boundary sliding, and grain boundary character on mechanical behavior. The project leads to the development of a processing methodology useful to enhance the mechanical behavior of high-temperature structural materials. The educational outreach component incorporates the research tools used in the research portion of the project and contributes to an increase in the number of undergraduate students majoring in materials science and engineering (MS&E).
