||Many alloy systems continue to play a vital role in structural applications at elevated temperatures for the aerospace, automotive, and power generation industries. Various phase transformations that take place during fabrication and post-processing determine the desired properties of these alloys, whereas others that arise during manufacturing or in operation could lead to failure. Understanding the mechanisms involved in these phase transformations and their effect on material properties is extremely important for the successful design and use of these alloys at elevated temperatures. This symposium aims at providing a setting to interested parties from academia, government, and industry for a fruitful discussion on recent experimental and computational advances in the field. Model, in development, and commercial alloy systems of interest include, but are not limited to, superalloys, steels, intermetallics, refractory metals, multi-principal element alloys, titanium alloys, and aluminum alloys.
