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 کاملSynthesis and Characterization of Ti-6Al-6Mo Prepared by Arc Melting Process
The Ti-6Al-6Mo alloy was arc-melted eight times from pure Ti, Al, and Mo. The Ti6Al-6Mo were analyzed by using an optical microscope, SEM-EDS, XRD and Vickers Hardness Tester. Corrosion test was performed by using Hank’s solution at 37 °C and pH 7.4. The optical micrograph showed a similar structure of this alloy. The microstructure of Ti 6Al6Mo was basketweave with lath. The map of Ti, Al an...
متن کاملEnhanced ultrasonically assisted turning of a β-titanium alloy.
Although titanium alloys have outstanding mechanical properties such as high hot hardness, a good strength-to-weight ratio and high corrosion resistance; their low thermal conductivity, high chemical affinity to tool materials severely impair their machinability. Ultrasonically assisted machining (UAM) is an advanced machining technique, which has been shown to improve machinability of a β-tita...
متن کاملUltrasonically assisted turning of NiTi based shape memory alloy
In this study, vibration cutting has been applied to machining of a novel material, NiTi based shape memory alloy (SMA), using a commercial ultrasonic piezoelectric transducer to vibrate an ISO insert CCMT geometry cutting tool. The effect of vibration in turning process was characterized by investigating the surface roughness of workpiece and surface quality assessment of machined surface usin...
متن کاملAfrl-rx-wp-tp-2008-4052 Random Heterogeneity Scales and Probabilistic Description of the Long- Lifetime Regime of Fatigue (preprint)
The long-lifetime fatigue regime is suggested to be a probabilistic realization of sequentially occurring mechanisms. We associate these mechanisms with the development of a ranking of heterogeneity scales in the material, with decreasing probability of occurrence in the order of increasing scale, at any given loading condition. The underlying drivers for these heterogeneity levels are an array...
