Available in PDF, EPUB and Kindle. Book excerpt: This report is a bibliography of the work reported in the literature on the effects of low temperature on the properties of structural materials. Some of the newer areas of cryogenic technology such as superconducting machinery involve environments which may subject the components to temperature as low as 4 K. Exposure of structural materials to such low temperatures affects their properties. This bibliography contains 963 references published between 1950-1976, arranged in chronological/alphabetical order. Combined material/property indexes are provided. (Author).

Available in PDF, EPUB and Kindle. Book excerpt: Gas turbines are widely used in industry for power generation and as a power source at hard to reach locations where other possibilities for electrical power supplies are insufficient. New ways of producing greener energy is needed to reduce emission levels. This can be achieved by increasing the combustion temperature of gas turbines. High combustion temperatures can be detrimental and degrade critical components. This raises the demands on the high temperature performance of the superalloys used in gas turbine components. These components are frequently subjected to different cyclic loads combined with for example dwell-times and overloads at elevated temperatures, which can influence the crack growth. Dwell-times have been shown to accelerate crack growth and change cracking behaviour in both Inconel 718, Haynes 282 and Hastelloy X. On the other hand, overloads at the beginning of a dwell-time cycle have been shown to retard the dwell-time effect on crack growth in Inconel 718. More experiments and microstructural investigations are needed to better understand these effects. The work presented in this thesis was conducted under the umbrella of the research program Turbo Power; "High temperature fatigue crack propagation in nickel-based superalloys", where I have mainly looked at fatigue crack growth mechanisms in superalloys subjected to dwell-fatigue, which can have a devastating effect on crack propagation behaviour. Mechanical testing was performed under operation-like cycles in order to achieve representative microstructures and material data for the subsequent microstructural work. Microstructures were investigated using light optical microscopy and scanning electron microscopy (SEM) techniques such as electron channeling contrast imaging (ECCI) and electron backscatter diffraction (EBSD). The outcome of this work has shown that there is a significant increase in crack growth rate when dwell-times are introduced at maximum load (0 % overload) in the fatigue cycle. With the introduction of a dwell-time there is also a shift from transgranular to intergranular crack growth for both Inconel 718 and Haynes 282. The crack growth rate decreases with increasing overload levels in Inconel 718 when an overload is applied prior to the dwell-time. At high temperature, intergranular crack growth was observed in Inconel 718 as a result of oxidation and the creation of nanometric voids. Another observed growth mechanism was crack advance along ?-phase boundaries with subsequent oxidation of the ?-phase. This thesis comprises two parts. Part I gives an introduction to the field of superalloys and the acting microstructural mechanisms related to fatigue and crack propagation. Part II consists of five appended papers, which report the work completed as part of the project.

Available in PDF, EPUB and Kindle. Book excerpt: Timely summary of state-of-the-art solid-state metal 3D printing technologies, focusing on fundamental processing science and industrial applications Solid-State Metal Additive Manufacturing: Physics, Processes, Mechanical Properties, and Applications provides detailed and in-depth discussion on different solid-state metal additive manufacturing processes and applications, presenting associated methods, mechanisms and models, and unique benefits, as well as a detailed comparison to traditional fusion-based metal additive manufacturing. The text begins with a high-level overview of solid-state metal additive manufacturing with an emphasis on its position within the metal additive manufacturing spectrum and its potential for meeting specific demands in the aerospace, automotive, and defense industries. Next, each of the four categories of solid-state additive technologies—cold spray additive manufacturing, additive friction stir deposition, ultrasonic additive manufacturing, and sintering-based processes—is discussed in depth, reviewing advances in processing science, metallurgical science, and innovative applications. Finally, the future direction of these solid-state processes, especially the material innovation and artificial intelligence aspects, are discussed. Sample topics covered in Solid-State Metal Additive Manufacturing include: Physical processes and bonding mechanisms in impact-induced bonding and microstructures and microstructural evolution in cold sprayed materials Process fundamentals, dynamic microstructure evolution, and potential industrial applications of additive friction stir deposition Microstructural and mechanical characterization and industrial applications of ultrasonic additive manufacturing Principles of solid-state sintering, binder jetting-based metal printing, and sintering-based metal additive manufacturing methods for magnetic materials Critical issues inherent to melting and solidification, such as porosity, high residual stress, cast microstructure, anisotropic mechanical properties, and hot cracking Solid-State Metal Additive Manufacturing is an essential reference on the subject for academic researchers in materials science, mechanical, and biomedicine, as well as professional engineers in various manufacturing industries, especially those involved in building new additive technologies.
