Experimental Determination of Texture and Mechanical Anisotropy of Tensile Properties in Commercially Pure Titanium Sheet

摘要

An experimental program was carried out to determine the relationship between texture and the sheet tensile properties. This investigation consisted of extensive testing of eight commercially pure titanium sheets. In each case, chemical analysis, microstructure, X-ray basal pole figure, and tensile properties were determined. The tensile properties were determined at 10-degree increments from the rolling to the transverse direction. In addition to determining the conventional yield strength, tensile strength, and elongation parameters, strain gages were used to obtain Young's modulus and Poisson's ratio in both the elastic and plastic zones. The sheets investigated had very similar textures, and it was shown that definite anisotropic characteristics were present. The interrelationship between anisotropy and texture is discussed in terms of single-crystal properties. (Author)
