Plastic anisotropy of textured ODS nickel-base alloy PM 1000

Strongly textured ODS nickel-base alloy PM 1000 with a pancake grain structure has been deformed in axisymmetric and plane strain compression at 1000degreesC and a true strain rate of 10(4) s(-1). The texture has been measured by neutron diffraction. Based oil the texture. Taylor factors have been calculated for the different deformation modes, The linear dependence of the strength on the Taylor factor indicates that the plastic anisotropy observed is due to the texture and not to the anisotropy of the grain structure.
