The data is exchanged between Hydism and iSIGHT.
In optimization result of 4 Schemes, the optimization effects of spray cone are not ideal, and the maximum reduction range of Saunter mean diameter is 18.2%, the minimum is 5.6%, so, the optimization effect of Saunter mean diameter is ideal.

Cold rolling reductions of 40% were applied to 50mm square strip samples.
Engler et al [3] compared two quantitative measures to derive the minimum number of single orientations required to adequately represent the texture of a given sample and so to assess the statistical significance of the microtexture data.

Fig. 1 Changes in the degree of crystallinity with the true rolling strain calculated from the integrated X-ray diffraction data
It must be considered from both crystalline and amorphous parts to study the work hardening, because there are different plastic deformation mechanisms and hardening mechanisms in the semi-crystalline polymer.
The X-ray results can be used to return the relationship between the crystallinity XC and the true strain ε: (2) The true stress strain curve of polypropylene during rolling is considered as the compression tests in this work, because the rolling reduction of each pass is very small [4].

On the other hand, it was revealed that a
reduction of flow stress does not always give an increment of elongation in this system as predicted
previously [9].
