In addition, the Cu-addedsteelhadaweakerrecrystallizationtexturethantheno-Custeel,butγ-fiberwasdevelopedbecauseofagingforalongtimebeforecold rolling.Consequently,thevolumefractionandsizeofε-Cuprecipitation,whichcausedtherecrystallizationbehavior,wereexaminedquantitatively. The analysis based on the subgrain growth model considering a temperature change in the precipitation state such as the volume fraction and particle diameter using Thermo-Calc. and DICTRA was effective.
