Abstract
Using JMatPro numerical simulation to determine the range of process parameters, the solution aging treatment of Ni30 superalloy was carried out, and the influence of different solution treatment temperatures on the microstructure and hardness of the alloy was studied. The results show that with the increase of solution temperature, the grain grows rapidly, the grain growth process conforms to Arrhenius formula, and the activation energy Q of grain growth is about 74.33kJ/mol. The maximum hardness value of the sample is 41.80HRC after solution aging treatment at 980°C.
