The variance in grain size is most likely due to the different recrystallization processes caused by the peak temperature and plastic deformation at both rotation speeds. Fig. 5

WebAug 7, 2024 · In general the structure of the normalised plate is finer. Plate bending can be split into two main categories, plate rolling and press braking. The latter consists of much tighter radii, therefore the risk of … WebThe size of grains at the top and bottom of the rolled plate converged to 0.65 mu m, while that of grains at the center of the plate increased with the number of ARB cycles.
