ODS Characterization Progress Report 06/27/08

[摘要] This progress report is intended to help keep track of the work that has been performed in characterizing ODS steels for the LIFE project. This specific report details the current status of the characterization of a 24% Cr, 1% Y{sub 2}O{sub 3} ODS steel obtained from Wayne King via Geoff Campbell. Since no pedigree of the material could be obtained, a baseline characterization was necessary prior to studying processing, welding, and corrosion behavior. This document details the results obtained from analysis performed using scanning electron microscopy (SEM), electron backscatter diffraction (EBSD) and energy dispersive spectroscopy (EDS). At the time of writing, transmission electron microscopy (TEM) and microhardness measurements have not been completed, and will be included in a future report. The results are presented in two sections: microstructure, and phase identification. As the names suggest, the first section will report on the microstructure in the general sense and include details such as grain size and texture, and the second section will include the identification of the phases present in the baseline material.
