Abstract : Knoop hardness measurements were made on the major planes of two sheets of commercially pure titanium and one of iodide titanium. Anisotropy of hardness was found to exist in the three unalloyed polycrystalline titanium materials tested. Each textured material manifested hardness variations on the major planes of the sheets and the harness measured in each instance was dependent on the orientation of the Knoop indenter. Further evidence of Knoop hardness variations caused by preferred orientation was found in the hardness difference existing between the rolling and cross-section planes. (Author)
