FIB/SEM/EBSD/EDS Study of the Grain boundary Character Effect on Precipitation
EMSL Project ID
26598
Abstract
INCOLOY Alloy 800H is a candidate material for the Next Generation Nuclear Plant. Its grain boundary character distribution has been found to be effectively adjusted by means of grain boundary engineering (GBE). The morphology and size of the thermal-induced precipitates at grain boundaries are strongly dependent upon grain boundary character. This project is to study the thermal and/or irradiation effects on these precipitates as a function of grain boundary types. Focused-ion-beam (FIB) is proposed to be employed for fabricating TEM specimens at selected grain boundaries identified by electron backscatter diffraction (EBSD) that is incorporated with the FIB. The integrated EDS and STEM will also be used to study the elemental distribution and microstructure.
