Available in PDF, EPUB and Kindle. Book excerpt: In several industrial fields (such as automotive, steelmaking, aerospace, and fire protection systems) metals need to withstand a combination of cyclic loadings and high temperatures. In this condition, they usually exhibit an amount—more or less pronounced—of plastic deformation, often accompanied by creep or stress-relaxation phenomena. Plastic deformation under the action of cyclic loadings may cause fatigue cracks to appear, eventually leading to failures after a few cycles. In estimating the material strength under such loading conditions, the high-temperature material behavior needs to be considered against cyclic loading and creep, the experimental strength to isothermal/non-isothermal cyclic loadings and, not least of all, the choice and experimental calibration of numerical material models and the selection of the most comprehensive design approach. This book is a series of recent scientific contributions addressing several topics in the field of experimental characterization and physical-based modeling of material behavior and design methods against high-temperature loadings, with emphasis on the correlation between microstructure and strength. Several material types are considered, from stainless steel, aluminum alloys, Ni-based superalloys, spheroidal graphite iron, and copper alloys. The quality of scientific contributions in this book can assist scholars and scientists with their research in the field of metal plasticity, creep, and low-cycle fatigue.

Available in PDF, EPUB and Kindle. Book excerpt: A compilation of data collected and maintained for many years as the property of a large aluminum company, which decided in 1997 to make it available to other engineers and materials specialists. In tabular form, presents data on the tensile and creep properties of eight species of wrought alloys and five species of cast alloys in the various shapes used in applications. Then looks at the fatigue data for several alloys under a range of conditions and loads. The data represent the typical or average findings, and though some were developed years ago, the collection is the largest and most detailed available. There is no index.

Download or read book Investigation of the Effects of Rapid Loading and Elevated Temperatures on the Mechanical Properties of Compressive and Column Members written by P. R. Dioguardo and published by . This book was released on 1962 with total page 148 pages. Available in PDF, EPUB and Kindle. Book excerpt: Short time tensile and compressive properties were evaluated for Rene' 41 and Haynes 25 sheet alloys at room temperature and 800 to 2200 F. Tests conducted at various strain rates (0.00001 to 0.1 in./in.sec) produced significant differences in strength, particularly at elevated temperatures. Creep properties, both tensile and compressive, were determined for the same alloys at temperatures of 1600 to 2200 F and times up to 15 minutes. At the higher stress levels, creep rates became very rapid and considerable amounts of plastic strain occurred in times of 1 sec or less. A preliminary study was conducted on the use of programmed, forced strain rate tests to predict short time creep properties.

Download or read book Creep and High Temperature Deformation of Metals and Alloys written by Stefano Spigarelli and published by MDPI. This book was released on 2019-12-12 with total page 212 pages. Available in PDF, EPUB and Kindle. Book excerpt: By the late 1940s, and since then, the continuous development of dislocation theories have provided the basis for correlating the macroscopic time-dependent deformation of metals and alloys—known as creep—to the time-dependent processes taking place within the metals and alloys. High-temperature deformation and stress relaxation effects have also been explained and modeled on similar bases. The knowledge of high-temperature deformation as well as its modeling in conventional or unconventional situations is becoming clearer year by year, with new contemporary and better performing high-temperature materials being constantly produced and investigated. This book includes recent contributions covering relevant topics and materials in the field in an innovative way. In the first section, contributions are related to the general description of creep deformation, damage, and ductility, while in the second section, innovative testing techniques of creep deformation are presented. The third section deals with creep in the presence of complex loading/temperature changes and environmental effects, while the last section focuses on material microstructure–creep correlations for specific material classes. The quality and potential of specific materials and microstructures, testing conditions, and modeling as addressed by specific contributions will surely inspire scientists and technicians in their own innovative approaches and studies on creep and high-temperature deformation.

Download or read book An Investigation of Threshold Stress in Dispersion Strengthened Aluminum Alloys written by Sachin Deshmukh and published by . 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.
