This book was released on 1978 with total page 22 pages. Available in PDF, EPUB and Kindle. Book excerpt: High cycle fatigue data of unnotched Ti-6Al-2Sn-4Zr-6Mo revealed no change in fatigue strength at 900 F compared to room temperature, 400 F, and 700 F. At 1000 F, the decrease in fatigue strength from that at 900 F and below becomes noticeable. At 1200 F the decrease is significant. The fatigue strength-life curve of specimens coated with electroless nickel and diffusion bonded, which were tested at 1000 F, falls midway between results of uncoated specimens tested at 1000 F and 1200 F. Microstructural changes occurring with time, at temperature, indicate a refinement of structure. Fractography reveals three distinct areas: an initial radial area which is a mixed mode of quasi-cleavage and intergranular fracture; followed by a radial fibrous zone, the result of dimpled fracture; and finally a shear lip which occurs by shear fracture.

Available in PDF, EPUB and Kindle. Book excerpt: About 35 years ago, thermal fatigue was identified as an important phenomenon which limited the lifetime of high temperature plant. In the intervening years many investigations have been carried out, primarily to give guidance on likely endurance (especially in the presence of time dependent deformation) but latterly, with the introduction of sophisticated testing machines, to provide knowledge of the underlying mechanisms of failure. A previous edited book (Fatigue at High Temperature, Elsevier Applied Science Publishers, 1983) summarised the state-of-the-art of high temperature fatigue testing and examined the factors influencing life, such as stress state, environment and microstructural effects. It also considered, in some detail, cyclic crack growth as a more rigorous approach to life limitation. The aim of the present volume (which in style and format follows exactly the same lines as its predecessor) is once again to pursue the desire to translate detailed laboratory knowledge into engineering design and assessment. There is, for example, a need to consider the limitations of the laboratory specimen and its relationship with engineering features. Many design procedures still rely on a simple endurance approach based on failure of a smooth specimen, and this is taken to indicate crack initiation in the component. In this volume, therefore, crack propagation is covered only incidentally, emphasis being placed instead on basic cyclic stress strain properties, non-isothermal behaviour, metallography, failure criteria and the need for agreed testing procedures.

This book was released on 1998 with total page 18 pages. Available in PDF, EPUB and Kindle. Book excerpt: The results of an experimental investigation of load-controlled isothermal low cycle fatigue behavior of a titanium matrix composite (TMC) are discussed. The TMC was composed of Ti-6Al-2Sn-4Zr-2Mo matrix (wire) reinforced with silicon-carbide (Trimarc-1)TM fibers. The composite panels were constructed by alternating layers of matrix wire and fiber using a wire-winding technique. The panels were unidirectional with a [0]10 layup and fiber volume fraction ? 0.29. The longitudinal fatigue data showed good correlation with other TMC systems at both positive and negative stress ratios. The Walker equation was successful at correlating the longitudinal S-N data for stress ratios R = -1.3 and 0.1, and for predictions at R = 0.5 and 0.7. The maximum fiber stress versus cycles to failure for several unidirectional TMC systems at similar test conditions consolidate to a narrow band, indicating that the life is fiber dominated. The S-N behavior of the TMC, subjected to transverse fatigue loading, was successfully predicted using the matrix S-N data and a net-section model.

Available in PDF, EPUB and Kindle. Book excerpt: Comprehensive datasheets on more than 60 titanium alloys More than 200 pages on metallurgy and fabrication procedures Input from more than 50 contributors from several countries Careful editorial review for accuracy and usefulness. Materials Properties Handbook: Titanium Alloys provides a data base for information on titanium and its alloys, and the selection of specific alloys for specific applications. The most comprehensive titanium data package ever assembled provides extensive information on applications, physical properties, corrosion, mechanical properties (including design allowances where available), fatigue, fracture properties, and elevated temperature properties. The appropriate specifications for each alloy are included. This international effort has provided a broad information base that has been compiled and reviewed by leading experts within the titanium industry, from several countries, encompassing numerous technology areas. Inputs have been obtained from the titanium industry, fabricators, users, government and academia. This up-to-date package covers information from almost the inception of the titanium industry, in the 1950s, to mid-1992. The information, organized by alloy, makes this exhaustive collection an easy-to-use data base at your fingertips, which generally includes all the product forms for each alloy. The 60-plus data sheets supply not only extensive graphical and tabular information on properties, but the datasheets also describe or illustrate important factors which would aid in the selection of the proper alloy or heat treatment. The datasheets are further supplemented with back-ground information on the metallurgy and fabrication characteristics of titanium alloys. An especially extensive coverage of properties, processing and metallurgy is provided in the datasheet for the workhorse of the titanium industry, Ti-6Al-4V. This compendium includes the newest alloys made public. even those still under development. In many cases, key references are included for further information on a given subject. Comprehensive datasheets provide extensive information on: Applications, Specifications, Corrosion, Mechanical Design Properties, Fatigue and Fracture

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.
