Fe-Cr based alloys are of interest for various nuclear structural and cladding applications. In this study, Fe and Cr powders are milled together for different durations (2, 5, 8, 10, 12, 15 and 20 h) with varying Cr content (6-14 wt%). Powder characteristics such as crystallite size, lattice strain and powder size are evaluated. The 10 h milled powder was consolidated via spark plasma sintering at a temperature of 1273 K with a dwell time of 45 min. Effects of sintering parameters on densification, hardness and grain size are examined. The grain size increased with increasing sintering temperature and dwell time. This study is expected to lead to our understanding of the simple Fe-Cr system, which will be used to obtain fundamental information on grain boundary properties via in situ deformation studies on irradiated alloys. The work is supported by the Idaho National Laboratory.
