The (040)[alpha] pole figure of BBST samples (billet tube, (Fig.
Figure 15 presents X-ray diffraction patterns of billet tubes formed in BBST at 150, 160, and 170[degrees]C corresponding to effective strains of 0.
Figure 16 shows the X-ray diffraction patterns of OPP tube samples after BBST tests at 150, 160, and 170[degrees]C and effective strains of 0.
The orientation factor of the BBST billet tube sample at 150[degrees]C move slightly toward positive side of the transverse direction from the origin.
From this origin, orientation factor of BBST billet tube samples tested at 160[degrees]C moves toward equal biaxial strain state, whereas the orientation factor for the BBST billet tube sample at 170[degrees]C moves in the extrusion direction only.
II, the 1998 seed for BBST Cycle 2 was depleted; therefore, 1999 seed of BBST Cycle 2 was used for this population.
