Abstract

Abstract: A series of experiments of annealing for tailor rolled blank (TRB) of CR340 were carried out in order to study the microstructure and properties. The effects of the annealing temperature and time on the microstructure and properties of TRB in the area with different thickness were analyzed， and the reasons of different properties of TRB after annealing were explored. The results showed that differences of the microstructure and properties of TRB were determined by the amount of cold deformation，annealing temperature and holding time. By fitting the experimental data， the corresponding relationship between the yield strength and the elongation of TRB in the area of different thickness and the annealing temperature and holding time， and the function of the hardness and yield strength of TRB after annealing were established，which provide a reference for formulating the annealing processes and controlling microstructure and properties of TRB.

Key words: TRB(tailor rolled blank), annealing, recrystallization, yield strength, elongation
