Effect of Texture on the Charpy Impact Energy of Some Titanium Alloy Plate

Abstract

An investigation to determine the anisotropic nature of toughness due to texture in titanium and titanium alloy plate was conducted. Standard Charpy V-notch specimens were machined at ten-degree increments from the rolling to the transverse direction with notch orientation either parallel or perpendicular to the plate surface. Basal pole figures were determined along with impact energy, tensile properties, and microstructure. The study revealed that significant toughness variations can be found in titanium plate as a function of specimen and notch orientation. This impact energy anisotropy can be related to texturing with normal fibering effect being small or absent. An explanation of the toughness variation on a simplified crystallographic slip basis is given. Titanium plate studied includes commercially pure, Ti-6Al-4V, Ti-4Al-4V, Ti-4Al- 4Mn, and Ti-8Mn.
