Symposium on Elevated Temperature Applications of Materials for Fossil,
Nuclear, and Petrochemical Industries

Crowne Plaza Seattle / Seattle, WA

April 3-5, 2018



Session 1: Materials Properties of Candidate Materials
Addresses characterizing and understanding the role of material properties on safe operation and acceptable long term performance of pressure equipment operating at high temperatures; e.g. long term and very long term creep data, aging effects, environmental degradation, thermal fatigue; long term stability of new complex alloys. Covers development of newer materials such as nonmetallic materials, advanced austenitic stainless steel and nickel-based alloys, creep strength enhanced ferritic steels as well as the role advanced computational modeling tools can play in predicting materials behavior.

Session 2: Fabrication, Construction, and Heat Treatment Methods
Addresses the unique aspects of fabrication, welding, heat treatment, and construction of candidate advanced alloys and the effect these operations can have on long term material behavior and performance.

Session 3: Failure Mechanisms in Elevated Temperature Regime
Addresses plasticity and ductile rupture, creep and creep-fatigue failure, corrosion unique to environment such as fireside and internal corrosion / oxidation, embrittlement, loss of toughness, tensile or rupture ductility after long periods of service, carburization and decarburization.

Session 4: Elevated Temperature Design Methods
Addresses theoretical and practical design methods and predictive models to assure safe and reliable operation of equipment and components exposed to elevated temperature conditions. Covers experience, both international and domestic, with existing methods; development of new methodologies including simplified methods, full inelastic methods and creep-fatigue damage evaluation that emphasize the role of modern computer technology and finite element methods; and validation through comparison with service experience, testing of components, key features and specimens and comparison with rigorous inelastic analyses. It also addresses various methods of evaluating external pressure and axial compression of cylindrical, spherical, and conical shells in the creep regime using theoretical and numerical methods.

Session 5: Experience with Subcritical/Supercritical Boilers, Petrochemical Components, and Advanced Nuclear Vessels at Elevated Temperatures
Addresses real operating experience of the impact of elevated temperatures on the life of boilers, vessels, turbine, piping, and other components in fossil fueled and nuclear power plants, and in petrochemical and process plants. Effects of long-term service, cyclic operation, creep-fatigue damage, corrosion and oxidation are of special interest. This may include successful and problematic experiences including operational testing and laboratory examinations.

Session 6: Global Codes and Standards Requirements
Covers recently incorporated or to be incorporated revisions or additions to industry codes and standards that provide improved analysis methods for creep damage, high temperature ratcheting, and creep-fatigue interactions, including simplified code approaches for these phenomena. Qualification of new high temperature materials for inclusion in codes and standards as well as new fabrication and inspection techniques for high temperature piping and components are also of interest. Discussions include in-service inspection techniques, code-based flaw evaluation methods for elevated temperature service, and key standards development activities by International Working Groups (IWGs) under ASME Code Committees.
