. But the grain of ZK60(0.9Y)alloy is more fine and the growth amplitude of annealed grain is less than that of ZK60 alloys after annealing at 300-400 ℃. The grain size is 20 μm and σb is 226.9 MPa when ZK60(0.9Y) alloy after annealing for 120 min at 400 ℃. The calculation result shows that the activation energy of grain boundary migration of ZK60 alloy recrystallization is increased from......
