A Study of the Tensile Deformation and Fracture Behavior of Commercially Pure Titanium and Titanium Alloy: Influence of Orientation and Microstructure

Abstract

In this paper, the tensile deformation and fracture behavior of commercially pure titanium and the titanium alloy (Ti-6Al-4V) are presented and briefly discussed. Samples of both commercially pure titanium and the Ti-6Al-4V alloy were prepared from the as-provided plate stock along both the longitudinal and transverse orientations. The specimens were then deformed to failure in uniaxial tension. The intrinsic influence of material composition and test specimen orientation on microstructure, tensile properties, and resultant fracture behavior of the two materials is presented. The conjoint influence of intrinsic microstructural features, nature of loading, and specimen orientation on tensile properties of commercially pure titanium and the Ti-6Al-4V alloy is highlighted. The fracture behavior of the two materials is discussed taking into consideration the nature of loading, specimen orientation, and the role and contribution of intrinsic microstructural effects.

Selective Laser Melting of Titanium Alloys and Titanium Matrix Composites for Biomedical Applications: A Review

“…As shown in Table , the mechanical properties of SLM‐produced CP–Ti including tensile and hardness properties show that SLM can fabricate parts with superior properties to those processed by using traditional methods . As evident, the yield strength ( σ 0.2 ) and the ultimate tensile strength ( σ UTS ) of SLM‐produced CP–Ti are 555 and 757 MPa respectively, which are superior to the corresponding properties for sheet forming and full annealed conditions, and without distinct reduction in ductility. Moreover, the compressive properties of SLM‐produced CP–Ti samples (1 136 MPa) are higher than those of typically processed and deformed CP–Ti samples (820 and 900 MPa, respectively).…”

Influence of hydrogen on mechanical properties of pure titanium T40 (grade 2) and TA6V ELI (grade 23): a local approach of fracture

“…The main evoked hydrogen-assisted damage mechanism in titanium alloys is the formation of hydrides, however, this mechanism is mainly mentioned when the limit of hydrogen solubility is exceeded which leads to the formation of hydrides [2]. This does not exclude that other mechanisms may also play a role in the embrittlement, and more particularly when the structure is mechanically stressed, and the titanium alloy has a particular metallurgy (phases, textures …) [3,4]. So it is necessary to study the influence of the metallurgical states and the hydrogen concentrations on the mechanical behaviour of titanium alloys, this then requires a better understanding of the contribution of several conditions of CP (hydrogen concentrations below the solubility and until hydrides formation) on the mechanisms of fracture.…”

A Review on Biomedical Titanium Alloys: Recent Progress and Prospect

“…the ratio of strength to density), excellent corrosion resistance, and superior biocompatibility . During the development of Ti, most Ti products, such as commercially pure Ti (CP–Ti), Ti alloys, and Ti‐based composites, have been designed for the industries of aerospace, military, automobiles, medicine, jewelry, and mobile phones. Most importantly, due to the low density, high strength, high corrosion resistance, complete inertness to body environment, superior biocompatibility, low elastic modulus, high capacity to join with bone and other tissues, Ti and its alloys are regarded as the highly desirable choice for orthopaedic implants .…”
