Symposium Energy Materials 2017: Materials in Clean Power
Presentation Title Manipulating Creep through Modifying Gamma Prime Coarsening Rate in Haynes 282 for A-USC Power Plants
Author(s) Jeffrey A. Hawk, John S Sears, Paul D Jablonski
On-Site Speaker (Planned) Jeffrey A. Hawk
Abstract Scope Haynes 282 has been proposed for Advanced Ultra Supercritical (A-USC) energy applications. Haynes 282 is a gamma prime strengthened nickel superalloy that also contains various carbide phases. The alloy has good high temperature strength and excellent creep resistance. However, components for use in A-USC conditions must also be microstructurally stable for long times (i.e., 100,000 hours). The research performed at NETL highlights changes in the Ti/Al ratio and its effect on gamma prime coarsening rate and concomitant effect on creep life. The important strengthening features in Haynes 282 have been documented through use of TEM and ThermoCalc modeling, and then speaks to its long-term stability (i.e., gamma prime and carbide coarsening) based on microstructures from various selected creep tests as well as from isothermal exposure experiments through 20,000 hours. The creep behavior of Ti/Al ratio modified Haynes 282 is then compared against creep in preferred chemistry Haynes 282.
