Abstract. Powder metallurgy HIP and extrusion processing conditions were investigated in a FeCrAl alloy (Fe-Cr-Al-Mo based PM-C26M) for accident tolerant fuel cladding applications. The powder size range, HIP temperature (900 ~ 1100°C), HIP time (2 hours vs. 4 hours) were varied in lab-scale experiments, using argon gas atomized powder. The resulting density, grain size distribution, and retained plastic strain were characterized to recommend the HIP condition with full consolidation, fine grain size for formability, and good powder economics. The subsequent extrusion process was also studied in the temperature range of 950 ~ 1050°C as well as post annealing conditions. Based on the microstructure evaluation, sensitivity of HIP and extrusion process parameters were better understood.
