(3) Significant tensile anisotropy was observed for 4A, 4Ba, 4Bc
and 4C. The YS in the TD direction was always higher than ED
and ND directions. For sample 4Ba, an astonishing FE of 9%
was achieved in the ED direction. For sample 4Bc, the mechanical
properties (YS and FE) in ED and ND had similar
characteristics.
