Study on the Microstructures and Properties of middle-carbon-steel Rolled Pieces during Cross Wedge Rolling

摘要：

　　The rolling process of the three-roll cross wedge rolling with non-uniform temperature field was simulated with the finite element method (FEM).The distribution of the temperature and equivalent strain in radial section of rolled pieces was analyzed.The microstructures and properties of different positions in radial section were investigated.The results indicate that the temperature field and equivalent strain are ring-likely distributing in the radial section of rolled pieces.There are high temperature and small strain in the center.The temperature decreases and the strain increase gradually from the center to surtace.The microstructures and properties of rolled pieces are different in different positions.The microstructure in the center consists of pearlite and proeutectoid ferrite,while the surface consists of cementite particles and fine ferrite.
