dispersoids caused by recrystallization, which may efficiently promote heterogeneous precipitation during air quenching. More than 0.05% Zr can significantly decrease the quench sensitivity relative... to decreased quenching rate is called quench sensitivity, which is primarily caused by heterogeneous precipitation on dispersoids and (sub) grain boundaries[4-6]. The quench sensitivity is influenced by degree......
