Paper Title:
Study on Direct Annealing Process of Hot-Rolled Plate
  Abstract

To study the transmutation of organization and texture on direct annealing process of hot-rolled plate. Different annealing experiments were done in the lab. The annealed samples are from steel grade of SPHC. To check the organization of the annealed samples by optical microscopy, to measure grain size by Micro-image Analysis & process software. To measure the mechanical properties by the room temperature tensile test. To check AlN by TEM and EDX.To measure texture by texture measuring instrument, and the data was collected on a computer, using two-step calculation of ODF, measured with constant 45° section of graph. When annealing temperature of the samples reaches 875 °C or more, a relatively low strength , high n value, and high r value is received, but if the holding time is longer, grain coarsening occurs at the time,so the annealing temperature is not more than 925°C.When annealing temperature reaches 875 °C, AlN increased slightly, and the texture is not obvious.
