This book was released on 1961 with total page 54 pages. Available in PDF, EPUB and Kindle. Book excerpt: IN THE SOLUTION TREATED AND AGED CONDITION, Ti4Al-3Mo-1V has a higher ultimate strength than does Ti-2.5Al-16V, but the two alloys are about even in yield strength and elongation. In the solution-treated condition, Ti-4Al-3Mo-1V is unquestionably stronger than Ti-2.5Al-16V. These conclusions are independent of producer. There is not much difference in the same alloy produced by different companies. The alloys developed under the Titanium-Alloy Sheet-Rolling Program would not endure the most critical interpretation of release property specifications. On the other hand, these alloys come reasonably close to specifications. A complete set of release property specifications is available only for specimens that have been solution treated and aged. Such specimens do not all exhibit the desired ultimate and yield strength, but the percentage of rejects is small enough to be encouraging. (Author).

Book excerpt: The [alpha]-[beta] Ti-6% Al-4% V (Ti64) alloy can be heat treated to meet the specified requirements of the applications. The as-received material from SLAC was given a solution heat treatment (SHT) to have a good strength and ductility combination. The SHT was done at 200 C below the Beta transus of 990 C for 15 min and air-cooled to 20 C. The designed microstructure consists of [beta] phase precipitates within the [alpha] phase matrix. The characterization of the as-received Ti64 alloy sheet microstructure reveals equiaxed, 10 [mu]m-sized grains on the flat surface and finer, 8 [mu]m-sized grains in the through thickness. Figures 1 and 2 show the microstructure of the alloy. The typical Ti64 microstructure is lamellar structure, consisting of alternating [alpha] and [beta] phases. In order for the alloy to have the micron sized, equiaxed grains, it had to undergo extensive wrought processing. The Vicker's microhardness numbers (VHN) showed that the slightly larger grained flat surface had a higher averaged value than the through thickness; 33 kg/mm2 vs. 30 kg/mm2. The residual effect of wrought processing is still present even after the SHT to cause the small difference in the hardness values. The results of tensile tests conducted at LLNL and at BNL are given in Tables 2 and 1 in Appendices 1 and 2, respectively. The effects of the irradiation dosage damage on the tensile properties of the Ti64 are presented in Appendix 2. The as-received tensile specimens are not the standard specimens for testing. As shown in Attachment, Figure 1, only the 6 mm length is used in the reduced gage section of the specimens. As a result, a small change in the gage length will translate to a higher percentage change in elongation, giving higher elongation values than using the 30 mm length of the specimen. Since most of the deformation is concentrated in the reduced gage section, the present results are more accurate measurement of ductility. The Ti64 specimens failed in the center of the gage section. The Ti64 alloy contains extra low interstitials (ELI). There are an advantage and a disadvantage to having ELI. The advantage is that the alloy can exhibit good ductility since there is no effective deformation hindrance to mitigate the deformation twinning. The strength of the alloy is predominantly obtained from fine, equiaxed a grains. Given only the SHT, the alloy exhibits an adequate strength and ductility combination. The disadvantage of ELI is that the Young's modulus is sensitive to composition and heat treatment. The present alloy displays slightly lower Young's modulus values than the reported value of 108 GPa with the comparable SHT [1]. If needed, higher Young's modulus and strength can be obtained with subsequent aging treatment. The fracture surfaces of the specimens suggest ductile, dimple failure. Figure 3 shows the representative fracture characteristics of SHT Ti64. The cross-sectional view of the broken specimen has the appearance of extensive deformation prior to fracture (see Fig. 3a). The contribution of microstructure is clearly seen in the fracture surface, where the larger dimples represent the [alpha] phase since the dimple sizes are equivalent to the grain size. The smaller dimples are surmised to be [beta] precipitates. In addition to dimples, the fracture surface contained some sheared grains, indicated by the arrow in Figure 3b. It is inferred that since the deformation mechanism is twinning, it could be the twin interface separation.

This book was released on 1972 with total page 21 pages. Available in PDF, EPUB and Kindle. Book excerpt: Elevated temperature tensile properties of the Ti-6Al-4V, ELI grade alloy were determined and a forming temperature range was selected. A 7-foot-diameter hemisphere was hot-press formed from a 4-inch-thick plate according to laboratory-developed parameters. Mechanical property tests were conducted on the plate material before and after hot forming and after heat treating of the formed material. Results of these tests showed a lower tensile yield strength after hot forming and restoration of this property after heat treatment. The results indicate that a tensile yield strength of 120,000 pounds per square inch can be obtained throughout the thickness of the formed hemisphere after appropriate heat treatment.

Available in PDF, EPUB and Kindle. Book excerpt: In Ti-10-2-3 a variety of aged microstructures with different volume fractions and morphologies of primary and secondary alpha and also grain boundary alpha has been tensile tested. The results can be summarized as follows: (1) For a constant volume fraction of primary alpha it is possible to vary the yield stress in a wide range; it is also possible to reach comparable yield stress levels for different volume fractions of alpha by an appropriate choice of aging temperatures and times as well as heating up rates to the aging temperatures; (2) Increasing the volume fraction of primary alpha reduces the ductility at comparable yield stresses for the alpha-aged conditions. Only the beta-ST conditions with no primary alpha are an exception. They have lower ductilities than the (alpha + beta) ST conditions. The omega-aged microstructures have the lowest ductilities at comparable yield stresses; (3) The differences in ductilities between the (alpha + beta) ST and alpha-aged, the beta-ST and alpha-aged and the omega-aged microstructures are qualitatively related to different fracture modes; and (4) Microstructures from a different forging which instead of the above tested globular primary alpha have elongated primary show lower ductilities at comparable yield stresses.

Book excerpt: Designed to support the need of engineering, management, and other professionals for information on titanium by providing an overview of the major topics, this book provides a concise summary of the most useful information required to understand titanium and its alloys. The author provides a review of the significant features of the metallurgy and application of titanium and its alloys. All technical aspects of the use of titanium are covered, with sufficient metals property data for most users. Because of its unique density, corrosion resistance, and relative strength advantages over competing materials such as aluminum, steels, and superalloys, titanium has found a niche in many industries. Much of this use has occurred through military research, and subsequent applications in aircraft, of gas turbine engines, although more recent use features replacement joints, golf clubs, and bicycles.Contents include: A primer on titanium and its alloys, Introduction to selection of titanium alloys, Understanding titanium's metallurgy and mill products, Forging and forming, Castings, Powder metallurgy, Heat treating, Joining technology and practice, Machining, Cleaning and finishing, Structure/processing/property relationships, Corrosion resistance, Advanced alloys and future directions, Appendices: Summary table of titanium alloys, Titanium alloy datasheets, Cross-reference to titanium alloys, Listing of selected specification and standardization organizations, Selected manufacturers, suppliers, services, Corrosion data, Machining data.
