Abstract : The variations in normal and planar anisotropy in rolled metal products are shown to be functions of crystallographic structure. Each type (cubic and hexagonal) of crystallographic structure exhibits a characteristic strain ratio versus orientation curve. The average normal anisotropy parameter is linearly related to the 45 degrees strain ratio for both the cubic and hexagonal systems. Linear relationships were also found between the degree of planar anisotropy parameter and both the normal anisotropy and the strain ratio at 45 degrees in the cubic systems. No relationships were determined for the hexagonal close-packed structures although certain trends were noted. (Author)
