(S030_1)Microstructural Evolution in Static and Dynamic Ferrite Transformations of 10Ni-0.1C steel

摘要

Refinement of ferrite grains is one of the effective methods to improve strength and toughness simultaneously in steels. Dynamic ferrite transformation, which is a ferrite transformation occurring during deformation of austenite, can achieve very fine ferrite grains 1). However, there remains uncertainty about the difference between dynamic ferrite transformation and static ferrite transformation from deformed austenite. The present study investigated the microstructural evolution in the dynamic and static ferrite transformations.
