Book excerpt: The effects of heat treating environmental conditions on the stress-corrosion-cracking resistance of several titanium alloys have been studied. The alloys studied in this investigation were the Ti-8Al-1Mo-1V, Ti-7Al-1Mo-1V, Ti-6Al-4V, and Ti-7Al-2.5Mo alloys. Precracked cantilever type specimens were heat treated in either an inert atmosphere or in vacuum and tested in a 3.5 per cent salt water solution. A comparison of the stress intensity required for failure in salt water with that required for "dry" mechanical fracture indicates that all of these alloys become essentially insensitive to the aqueous environment when vacuum solution annealed and helium gas cooled. Similar heat treatments in argon or helium developed a wide range in level of stress-corrosion-cracking resistance for these alloys; the level was dependent upon the temperatures used. The environmental conditions associated with aging treatments at 1200F following the solution anneal appear to have little effect on the stress-corrosion-cracking resistance of these alloys. Comparison of the stress-corrosion-cracking data with hydrogen content before and after treatment indicates a close connection between stress-corrosion-cracking sensitivity and hydrogen content in the material even at very low hydrogen levels. These results suggest that hydrogen contained in the metal may play an important role in the stress-corrosion cracking process of titanium alloys.

Available in PDF, EPUB and Kindle. Book excerpt: The elevated temperature stress-corrosion cracking behavior of several titanium alloys was investigated. The results indicate varying degrees of susceptibility, depending on alloy, test conditions, heat treatment, and so on. The need for additional work and refinement and standardization of test conditions is evident from the variations in test results reported here and by other researchers. Materials tested included sheet alloys Ti-8Al-1Mo-1V, Ti-6Al-4V, Ti-5Al-2.5Sn, Ti-13V-11Cr-3Al, Ti-4Al-3Mo-1V, and extrusion alloys Ti-8Al-1Mo-1V, Ti-6Al-6V-2Sn, Ti-6Al-4V, and Ti-7Al-4Mo. Test exposure temperatures from 500 to 650 F were used. Other test variables were salt type and thickness, heat treatment strength level, stress level, fabrication effects (spotwelding, fusion welding, bend forming, and so on) and exposure time. It has not been established whether laboratory stress-corrosion behavior in titanium alloys can be a problem in actual service; however, the approach at Lockheed will be to select and control materials for use in SST construction which are shown to be unaffected in laboratory elevated temperature stress-corrosion testing.

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.

Available in PDF, EPUB and Kindle. Book excerpt: The material is contained in more than 500 datasheet articles, each devoted exclusively to one particular alloy, a proven format first used in the complementary guide for irons and steels. For even more convenience, the datasheets are arranged by alloy groups: nickel, aluminum, copper, magnesium, titanium, zinc and superalloys. The book provides very worthwhile and practical information in such areas as: compositions, trade names, common names, specifications (both U.S. and foreign), available products forms, typical applications, and properties (mechanical, fabricating, and selected others). This comprehensive resource also covers the more uncommon alloys by groups in the same datasheet format. Included are: refractory metals and alloys (molybdenum, tungsten, niobium, tantalum), beryllium copper alloys, cast and P/M titanium parts, P/M aluminum parts, lead and lead alloys, tin-rich alloys, and sintering copper-base materials (copper-tin, bronze, brass, nickel silvers).

Available in PDF, EPUB and Kindle. Book excerpt: Susceptibility of titanium alloys to hot-salt stress-corrosion cracking increased as follows: Ti-2Al-11Sn-5Zr-0.2Si(679), Ti-6Al-2Sn-4Zr-2Mo(6242), Ti-6Al-4V(64), Ti-6Al-4V-3Co(643), Ti-8Al-1Mo-1V(811), and Ti-13V-11Cr-3A1(13-11-3). The Ti-5Al-6Sn-2Zr-1Mo-0.25Si(5621S) alloy was both the least and most susceptible depending on heat treatment. Such rankings can be drastically altered by heat-to-heat and processing variations. Residual compressive stresses and cyclic exposures also reduce susceptibility to stress-corrosion. Simulated turbine-engine compressor environmental variables such as air velocity, pressure, dewpoint, salt concentration, and salt deposition temperature have only minor effects. Detection of substantial concentrations of hydrogen in all corroded alloys confirmed the existence of a hydrogen embrittlement mechanism.--P. [i].
