(1) As the temperature increases, the elongation of the sheet after N6 Nick Plate cold rolling increases first and then decreases, reaching a maximum at 500 ° C.

(2) After annealing at 350 ° C, a large number of unevenly distributed fine particles appeared between the grains that were originally deformed, and as the temperature increased to 450 ° C, there were obvious precipitated phases, and at the same time, impurity element aggregation occurred. When the recrystallization at ℃ was completed, it was equiaxed and the grain deformation caused by rolling had disappeared.

(3) N6 pure nickel is annealed at 500 ℃ × 1 h after cold rolling, the work hardening phenomenon of the plate is eliminated, and the comprehensive mechanical properties reach the best.
