Taking SA508-3 steel forging for steam generator as research object,the thermophysical parameters for the steel were calculated by JMatpro software.After heat treatment,the microstructure and hardness of the forging were simulated by Deform-3D software.And the experimental verification was carried out by small specimen physical simulation method.The results show that the microstructure and hardness of both the experimental test and numerical simulation are in good agreement.It can be seen that numerical simulation technology is an effective tool to determine the rationality of heat treatment process for large forgings,which has significant value in shortening production cycle and reducing cost.
