Available in PDF, EPUB and Kindle. Book excerpt: * Numerous line drawings with consistent format and units allow easy comparison of the behavior of a very wide range of materials * Transmission electron micrographs provide a direct insight in the basic microstructure of metals deforming at high temperatures * Extensive literature review of over 1000 references provide an excellent reference document, and a very balanced discussionUnderstanding the strength of materials at a range of temperatures is critically important to a huge number of researchers and practitioners from a wide range of fields and industry sectors including metallurgists, industrial designers, aerospace R&D personnel, and structural engineers. The most up-to date and comprehensive book in the field, Fundamentals of Creep in Metals and Alloys discusses the fundamentals of time-dependent plasticity or creep plasticity in metals, alloys and metallic compounds. This is the first book of its kind that provides broad coverage of a range of materials not just a sub-group such as metallic compounds, superalloys or crystals. As such it presents the most balanced view of creep for all materials scientists. The theory of all of these phenomena are extensively reviewed and analysed in view of an extensive bibliography that includes the most recent publications in the field. All sections of the book have undergone extensive peer review and therefore the reader can be sure they have access to the most up-to-date research, fully interrogated, from the world's leading investigators.· Numerous line drawings with consistent format and units allow easy comparison of the behavior of a very wide range of materials· Transmission electron micrographs provide a direct insight in the basic microstructure of metals deforming at high temperatures· Extensive literature review of over 1000 references provide an excellent reference document, and a very balanced discussion

This book was released on 2005 with total page 274 pages. Available in PDF, EPUB and Kindle. Book excerpt: "The high creep resistance of dispersion-strengthened alloys is a result of a threshold stress, which is determined by the attractive dislocation-particle interaction. The change of dislocation-particle interaction with temperature and the resultant threshold stress have been identified as research areas that need focused effort to improve the fundamental understanding of creep deformation of dispersion strengthened materials. Al-6Mg-2Sc-1Zr, Al-6Mg-1Sc-1Zr-10 vol.% SiC and Al-5Y2O3-10SiC systems were chosen for this study. Conventional creep experiments were carried out at constant load to study the creep mechanism and threshold stress in creep. The temperature of creep experiment performed was in the range of 423 to 573 K. (0.4 to 0.6 T[subscript m]). Creep data obtained in all the system mentioned above ranges over 8 orders of magnitude of strain rate. The analysis of the creep data obtained in the investigation have provided information on the creep characteristics of the alloy including the shape of the creep curve, the temperature dependence of the creep rate, the stress dependence of the creep rate and the details of creep mechanism. Microstructures were evaluated using optical, scanning and transmission electron microscopy. A threshold type creep behavior was measured and explained by observed dislocation-particle interactions. When threshold stress is incorporated into the analysis, it is shown that the stress exponent is ~5 and activation energy is close to the value for lattice self diffusion of pure aluminum. These results suggest that dislocation climb in the aluminum alloy is the rate controlling the creep process in this composite. The composite showed increased creep resistance at higher temperature compared to the unreinforced alloy. The dislocation-particle interaction was studied in composite by in-situ straining experiments in a transmission electron microscope. The experiments were conducted in order to find the deformation micromechanics involved at creep temperatures. In-situ TEM straining experiment showed that dislocations spend most of the time interacting with particle during the climb by-pass processes. Particle pinning strength was determined from the dislocation curvature and critical bow-out angle before the detachment at various temperatures and compared with the experimentally observed threshold stress values. The in-situ experiments support observations of attractive dislocation particle interaction obtained in last two decades by conventional TEM. At each temperature mean detachment stress values calculated from critical dislocation configuration lower than the experimental thresholds stress indicating a contribution from load transfer to reinforcement phase. A new positive climb model is proposed for the threshold stress in dispersion strengthen alloy. The model incorporates the concept of dislocation core relaxation at the particle-matrix interface which leads to attractive dislocation-particle interaction. The model predicts a temperature dependent threshold stress and the predicated creep behavior is in reasonable agreement with the behavior of an Al-Sc alloy"--Abstract, pages iv-v.
