THE ROLE OF MICROSTRUCTURE ON VARIOUS STAGES OF THE VERY HIGH CYCLE FATIGUE BEHAVIOR OF AN a + ß TITANIUM ALLOY, TI-6Al-2Sn- 4Zr-6Mo (PREPRINT)
The very high cycle fatigue behavior (10-10 cycles) of Ti-6246 has been investigated using ultrasonic fatigue techniques. In this regime of fatigue (0.4-0.6σYS), only certain microstructural regions are susceptible to fatigue damage accumulation, and lifetimes are related to the distribution of fatigue critical microstructural neighborhoods. Three distinct categories of crystallographic crack i...
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 کاملMicrostructural Evaluation of Ti-6AL-4V Alloy during Hot Deformation
Among the titanium alloys, Ti-6Al-4V is the most widely used. In the present work, the uniaxial hot compressive behavior of Ti-6Al-4V has been investigated under constant strain rates. A series of dilatometery experiments were carried out to determine the transformation temperatures at different cooling rates. Specimens were homogenized at 1050 °C for 10 minutes followed by fast cooling to dif...
متن کاملComparison of Mechanical Behavior and Microstructure of Continuous Cast and Hot Worked CuZn40Al1 Alloy (TECHNICAL NOTE)
The performance of components produced by conventional route of a thermo mechanical process and those produced by continuous casting is interesting from different aspects of economy and technology. The performance of products in their service depends on their properties which are strongly influenced by production routes. In the present work the hardness, tensile and tensile-impact behaviors of ...
