b'and produced by Cleveland Cliffs. The initial mechanical characterization for the three alloys included subsized tensile testing and microhardness testing and was performed at the UNM. The microstructural characterization was done at CSM and included traditional metallography, texture analysis using electron backscatter diffraction, dislocation density analysis via x-ray diffractometry, and precipitate analysis via transmission electron microscopy (TEM) and ToF-SIMS. This portion of the research generated two of the publications listed below. The next technical goal was the irradiation of each of the alloys. The irradiation was performed successfully using a 3 MeV tandem ion beam line in the Ion Beam Materials Laboratory at LANL. The last technical goal was the comparison of irradiation hardening amongst the alloys in addition to a detailed characterization of each alloy. To evaluate irradiation hardening, microhardness and nanoindentation were done at CSM. The characterization work was done primarily via scanning transmission electron microscopy also at CSM. Figure 4 shows graduate student Connor Rietema loading an irradiated sample into an electron microscope to prepare a specimen for analysis in the TEM. This portion of the research has been written up as a manuscript that is currently under review for publication. All threeFigure 4.
