Effect of Different Heat Treatment Processes on High Temperature Grain Size of 18CrNiMo7-6
In response to the phenomenon of mixed crystals in high-temperature carburization of 18CrNiMo7-6 after forging heat treatment,a comparative analysis was conducted on samples with different heat treatment processes and cooling rates after forging.It is believed that different heat treatment and cooling rates play a crucial role in the growth of AlN precipitation.Samples with rapid cooling have small and dispersed precipitates during the annealing process,which plays a role in pinning grain boundaries and hinders grain growth during high-temperature carburization,and prevents high-temperature carburization and crystal mixing.
