Properties and Texture Evolution of Cold Drawn High Carbon Steel Wires during Annealing Process

Electronic backscattering diffraction (EBSD) technology was used to research the texture evolution of the cold drawn high carbon steel wires during annealing process at 600 ℃. The microstructure and microhardness of the steel wires were researched by means of scanning electronic microscope and microhardness tester. The results show that during the annealing process at 600 ℃, with the prolongation of annealing time, the microstructure trans-formed from fibrous grains to equiaxed grains, the hardness decreased obviously. The texture type of the wires annealed for different times was the same as that of the as-drawn wires, which were main 〈110〉 fiber texture with some 111〈110〉 and 001〈110〉 circular fiber texture. With the prolongation of annealing time, the 〈110〉 fiber texture intensity decreased.
