The invention provides a
thermal simulation method of thermal-mechanical treatment of high strength automobile steel
impact specimen, and belongs to the technical field of
thermal simulation. The method comprises the steps of (1) based on the size the a standard
impact specimen, determining the
simulation specimen size, the
simulation specimen comprises a
simulation rectangle, two ladder platforms and two clamp ends, determining the high temperature thermal-mechanical treatment process parameters applied in the heat simulation process, (2)
welding a thermal couple on the surface of the simulation rectangle of the simulation specimen, (3) installing the simulation specimen on a thermal simulator, (4) conducting heat treatment to the simulation specimen, determining the average temperature area of the post-heated simulation specimen, (5) conducting
compression test to the simulation specimen, determining the post-compression average temperature area of the simulation specimen, (6) conducting cooling treatment to the simulation specimen, (7) checking the simulation specimen surface, (8)
processing the simulation specimen into a standard
impact specimen, and verifying if the impact process is effective. The method can enhance the
repeatability of the organization and preparation of the impact specimen of high strength automobile steel and the control precision of process parameters.
