About this Symposium
Meeting 2014 TMS Annual Meeting & Exhibition
Symposium Long-term Stability of High Temperature Materials
Sponsorship TMS Structural Materials Division
TMS: High Temperature Alloys Committee
Organizer(s) Mark Hardy, Rolls-Royce plc
Awadh Pandey, Pratt & Whitney Rocketdyne
David Mourer, General Electric Aircraft Engines
Jeffrey Hawk, National Energy Technology Laboratory
Scope The aim of this symposium is to examine the long term stability of high temperature structural materials. It is proposed that the technical focus is on (1) phase changes in bulk material, e.g. precipitation of phases, coarsening or morphology changes of existing phases, (2) surface degradation from high temperature environments, e.g. oxidation, hot corrosion, (3) exposure/stability effects on mechanical behavior, and (4) rejuvenation of initial microstructure. Within these technical fields, the organizers of the Symposium are looking for presentations/papers showing recent advances in understanding the effects of long term exposure on microstructure and material properties using experimental or modeling approaches or a combination of these two.
