Under monotonic loading, the martensitic phase transformation in the ultrafine-grained state is strongly favored. Under cyclic loading, the martensitic transformation behavior is similar to the coarse-grained condition, but the cyclic stress response is three times larger for the ultrafine-grained condition. %K martensitic transformation %K UFG %K cyclic loading %K AISI 304L %K stainless steel %K equal channel angular pressing %K tensile test %U http://www.mdpi.com/2075-4701/2/1/56
