The cooling rate in the quenching process of alloy products is one of the important factors affecting the alloy process, and rapid cooling can control the brittle carbide film at the grain boundary level. When the solid solution temperature of the alloy is higher than 1175, it is also easy to form carbide film at the pin ridge grain boundary. After long-term aging, the alloy shows a certain degree of aging hardening, which reduces the plasticity and high-temperature strength.
