This book was released on 2004 with total page 20 pages. Available in PDF, EPUB and Kindle. Book excerpt: The physical, mechanical, and corrosion properties of titanium and its alloys are attractive for applications in the U.S. Navy in view of design requirements for increased reliability with reduced maintenance and weight. The Naval Surface Warfare Center, in cooperation with Titanium Metals Corporation, developed the Ti-5Al-1Sn-1Zr-1V-0.8Mo (Ti-5111) alloy as a lower cost alternative to previous high-strength titanium alloys exclusive to Navy applications. The influence of heat treatment on the microstructure and mechanical properties was examined in the Ti-5111 alloy in both wrought and cast products. The effects of time and temperature on the microstructural evolution in this near-alpha alloy are assessed, and the relationships between microstructure and the corresponding tensile properties as well as impact and fracture toughness behavior are examined.

Available in PDF, EPUB and Kindle. Book excerpt: Titanium-Tantalum shape memory materials have widespread potential in biomedical applications due to their high degree of biocompatibility, favorable mechanical properties, high corrosion resistance and the possibility of exhibiting shape memory behavior 5' 6, 9. However, this system faces difficulties in processing due to the slow diffusion of Ta, with a melting point of 3269 K, and the sensitivity of shape memory materials on composition and processing history 8' 9 Dynamet Technology, Inc. has engineered a process in which these difficulties are overcome via powder metallurgy techniques, and the objective of this work was to characterize and explore the relationship between Dynamet's processing steps and the microstructure and properties of the Ti - 30 wt % Ta systems . Energy-dispersive x-ray analysis was used to quantify compositional gradients to verify homogeneity. Room temperature and high temperature x-ray diffractometry was used to identify phases present at temperatures ranging from room temperature up to 750 [degree]C. Hot extrusion without further heat treatment was found to be insufficient to produce a homogenous, fully dense alloy. Elongation, an indicator of potential shape memory behavior, was shown to increase with increased martensite phase fraction, which is thought to be dependent on cooling rate from above the austenite phase transformation starting temperature, Af. Finally, a phase transformation, likely that of martensite into beta-Ti, was verified to exist between 400 - 600 [degree]C.

This book was released on 2013 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Titanium alloys are employed in many advanced engineering applications due to their exceptional properties, i.e., a high strength-to-weight ratio, corrosion resistance, and high temperature strength. The performance of titanium alloys is known to be strongly affected by its inherent microstructure, which forms as a result of its thermo-mechanical processing. These microstructures produce compromise relationships between beneficial and detrimental effects on the alloy's performance. To study these structure-property relationships, two distinct crystal plasticity algorithms have been calibrated to data acquired from cyclic deformation experiments performed on three different Ti microstructures: (1) Ti-6Al-4V beta-annealed, (2) Ti-18 solution-treated, age-hardened (STA), and (3) Ti-18 beta-annealed, slow-cooled, age-hardened (BASCA). The calibrated models have been utilized to simulate fatigue loading of variant microstructures to investigate the influence of mean grain size, crystallographic texture, and phase volume fraction. The driving force for fatigue crack nucleation and propagation is quantified through the calculation of relevant fatigue indicator parameters (FIPs) and radial correlation functions are employed to study the correlation between favorably oriented slip systems and the extreme value FIP locations. The computed results are utilized to observe fatigue performance trends associated with changes to key microstructural attributes.

This book was released on 2017 with total page 154 pages. Available in PDF, EPUB and Kindle. Book excerpt: Titanium alloys are widely used for aerospace and biomaterial applications since their high specific strength, and high corrosion resistivity. Besides these properties, titanium is an excellent biocompatible material widely used for internal body implants. Because the products have complex geometries in both applications, Additive Manufacturing (AM) methods have been recently applied for production. AM methods can process a direct 3-D shape of the final product, decrease total production time and cost. However, high residual stress of the final product limits the application of AM components, especially the ones that are exposed to cyclic loading. In the present study, the initial microstructures and impact toughness of Ti6Al4V processed by EBM and CMT, and CP:Ti processed by SLM were experimented. In addition to initial microstructure and impact toughness, their response to different heat treatments were examined. Gleeble® 3500 was used for rapid heat treatment process. The change of mechanical properties due to different heat treatments were monitored with impact tests. Phase transformation kinetics of CP:Ti and Ti6Al4V were investigated with a Differential Scanning Calorimeter at slow heating and cooling rates. Microstructure examination was done with a scanning electron microscope. EBSD data was used to analyze the microstructure behavior. It is observed that toughness of the samples that are produced by powder-based AM methods were improved. Overall, residual stress, strain values, and grain orientation are the key elements that affected impact toughness AM produced components.

This book was released on 1969 with total page 108 pages. Available in PDF, EPUB and Kindle. Book excerpt: An open die, pancake forging study was conducted to determine the interplay of beta processing variables (temperature, deformation, and cooling rate) in controlling the as-worked (wrought) microstructure of Ti 6Al-4V. Emphasis was placed on obtaining the finest wrought beta structure and/or finest recrystallized beta grain size. Both macrostructures and microstructures were prepared and observed optically. It was found that the finest wrought structure was obtained by increasing the amount of deformation at the higher temperature for either air cooling or water quenching. Recrystallization ensues if the material is held in the beta field immediately after forging. (Author).
