Abstract(#br)This study investigated evolution of the microstructure of oxide dispersion strengthened Alloy 617 with annealing temperature. A mixture of prealloyed Alloy 617 and Y 2 O 3 powders was mechanically alloyed and consolidated by hot-extrusion at 1100<ce:hsp sp="0.25"/>°C. Hot extrusion dev...
