Deformation mechanism in nanolaminate FeCrAl alloys by in situ micromechanical strain rate jump tests at elevated temperatures

FeCrAl alloys have attracted extensive attention as one of the potential cladding materials for commercial light water reactors. Although creep behaviors coarse-grain been investigated at elevated temperatures, little is known on deformation mechanism fine-grain alloys. Here, we performed surface mechanical grinding treatment to fabricate nanolaminated ferritic In situ micropillar compression tests were applied determine underlying temperatures. The strain rate sensitivity and activation energy dominant estimated considering presence a threshold stress.
