Microstructure and Textural Evolution of Micro-carbon Steel during Continued Annealing Process

摘要：

　　The microstructure and textural evolution of micro-carbon DP steel during the heating stage of continued annealing process was studied using SEM,XRD and EBSD technique.Results show that,during the initial stage of recrystallization (from 720℃ to 750℃ ),the volume fraction of polygonal ferrite increased about 30%,and the deformed band easily induced the 001~112<110> oriented grains nucleation and growth priority.During the latter stage of recrystallization (from 750℃to 780℃),ferrite was almost fully recrystallized,<111>//ND fiber grain grew up and gradually swallowed <110>//RD grain.The intensity of 001 <110> orientation significantly increased due to carbide dissolution during high-temperature annealing,and the <111>//ND fiber texture hardly affected by transformation.
