Effects of Microstructure on Mixed-mode, High-cycle Fatigue Crack-growth Thresholds in Ti-6al-4v Alloy
A B S T R A C T Effect of microstructure on mixed-mode (mode I II), high-cycle fatigue thresholds in a Ti-6Al-4V alloy is reported over a range of crack sizes from tens of micrometers to in excess of several millimeters. Specifically, two microstructural conditions were exam-inedÐa fine-grained equiaxed bimodal structure (grain size $20 mm) and a coarser lamellar structure (colony size $500 m...
متن کاملInfluence of Microstructure on High-Cycle Fatigue of Ti-6Al-4V: Bimodal vs. Lamellar Structures
The high-cycle fatigue (HCF) of titanium alloy turbine engine components remains a principal cause of failures in military aircraft engines. A recent initiative sponsored by the United States Air Force has focused on the major drivers for such failures in Ti-6Al-4V, a commonly used turbine blade alloy, specifically for fan and compressor blades. However, as most of this research has been direct...
متن کاملFatigue 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 کاملFatigue endurance of Ti-6Al-4V alloy with electro-eroded surface for improved bone in-growth.
Ti-6Al-4V hour-glass shaped rotating beam specimens with duplex microstructure were processed by electric discharge machining (EDM). A comparatively high peak current of 29A was utilized in order to increase surface roughness for improved osteointegration. High cycle fatigue (HCF) tests were performed in rotating beam loading (R=-1) on these EDM specimens and results were compared with electrol...
متن کاملMixed-Mode, High-Cycle Fatigue-Crack Growth Thresholds in Ti-6Al-4V: A Comparison of Large and Small Crack Behavior
There are few experimental results to date describing the crack-propagation threshold behavior of short fatigue cracks under multiaxial loading conditions. To address this need, in the present study, the variation in mixed-mode, high-cycle fatigue-crack growth thresholds with crack size and shape are reported for a Ti-6Al-4V turbine blade alloy, heat treated to two widely different microstructu...
