Fatigue of Ti-6Al-4V
Metallic biomaterials have essentially three fields of use; these are the artificial hip joints, screw, plates and nails for internal fixation of fractures, and dental implants. Any of these devices must support high mechanical load and resistance of material against breakage is essential. High mechanical properties are needed for structural efficiency of surgical and dental implants. But their...
متن کاملTensile and fatigue strength of hydrogen-treated Ti-6Al-4V alloy
Tensile, fatigue and fractographic data on Ti-6AI-4V microstructures attained through a series of post-L3-annealing treatments which used hydrogen as a temporary alloying element are presented. Hydrogen-alloying treatments break up the continuous grain boundary 0c and colony structure, and produce a homogeneous microstructure consisting of refined s-grains in a matrix of discontinuous 13. These...
متن کاملFatigue and corrosion fatigue properties of Ti-6Al-4V implant grade titanium alloy in Ringer solution
Nowadays modification of metallic biomaterials which are used as implants for bone and hard tissues replacement is considered as an important subject. In the current study, corrosion fatigue properties of Ti-6Al-4V alloy investigated via Rotating-Bending standard test method and then, the results compared with the fatigue properties of the specimens tested in the same conditions. Scanning elect...
متن کاملEFFECTS OF TENSILE STRENGTH ON FATIGUE BEHAVIOR AND NOTCH SENSITIVITY OF TI-6AL-4V
In this research, rotating bending fatigue test at minimum to maximum stress ratio of R=-1 was used for investigating the fatigue behavior of Ti-6Al-4V alloy. Both smooth and notched specimens, with elastic concentration factor, kt, of approximately 3.6 and 4.1 were used for this purpose.In addition, the effect of variation in ultimate tensile strength, UTS, on the fatigue behavior of this allo...
متن کاملEffect of plasma welding parameters on the flexural strength of Ti-6Al-4V alloy.
The aim of this study was to assess the effect of different plasma arc welding parameters on the flexural strength of titanium alloy beams (Ti-6Al-4V). Forty Ti-6Al-4V and 10 NiCr alloy beam specimens (40 mm long and 3.18 mm diameter) were prepared and divided into 5 groups (n=10). The titanium alloy beams for the control group were not sectioned or subjected to welding. Groups PL10, PL12, and ...
