Abstract

The invention discloses a method for detecting the texture performance of a thermal simulation experiment material and belongs to the field of material detection. The method comprises the following steps of making a cylindrical sample by the material in a thermal simulation experiment, putting the cylindrical sample into a thermal simulation experiment machine, controlling the axial temperature gradient of the sample to obtain a uniform temperature zone in the middle of the sample, and carrying out controlled deformation and controlled cooling on the uniform temperature zone, wherein the length of the cylindrical sample is L0, the diameter of the cylindrical sample is d0, the length of the uniform temperature zone is l0, and the middle part of the sample is in a drum shape after the experiment. According to the method, the sample after the experiment can be made into detection samples such as a metallographic phase sample, a stretching sample and an impact sample, so that the texture characteristics of the material can be observed under different process conditions, and the strength, rigidity and ductility-toughness indexes of the material can be detected as well; the problems that the strength and ductility-toughness indexes of the material are difficult to measure after the thermal simulation experiment can be solved, and the accurate and reliable method is provided for the material research and the hot-machining process formulation.

Problems solved by technology

Large sample plane strain thermal simulation experiment provides a method and means for material development and process research, but it is not widely used at present, and some measurement and control problems need to be improved; and due to the large sample size, the uniformity of strain and temperature decreases , resulting in large differences in process conditions such as temperature, deformation and cooling speed of the same sample, and the accuracy of the research is reduced.
