The effect of dynamically recrystallized austenite on the martensite start temperature, Ms, in hot-deformed Fe-32% Ni alloy was studied by measuring its electrical resistance. Differing from the statically recrystallized structure, the dynamically recrystallized grains have heterogeneous dynamic substructures. The growing dynamic recrystallization grain with a dislocation density in a gradient distribution contains a few mobile dislocations near the grain boundary. These mobile dislocations promote the martensitic nucleation and increase the Ms temperature. © 2006 Elsevier B.V. All rights reserved.
