Available in PDF, EPUB and Kindle. Book excerpt: High Strength Low Alloy (HSLA) steels have been shown to posses high strength and toughness. Additionally, these steels can be welded without the normal preheating required by comparable HY-series steels. HSLA-100, 100 Ksi yield strength, contains increased amounts of copper, manganese and nickel over the currently certified HSLA-80. However, prior to use in Naval ship construction knowledge of the steels toughness behavior is necessary. Existing fracture mechanics models are not applicable to HSLA-100 because HSLA-100 has only 0.04% carbon and these models use carbides as the nucleation sites for cleavage fracture. This research is part of a program to investigate and model the micromechanics of deformation and fracture of HSLA-100. Tensile testing of hourglass shaped specimens was conducted at quasi-static strain rates. Individual tensile test temperatures ranged from 24 C to -196 C. True stress, corrected for necking, and true plastic strain were monitored throughout the tests. This allowed a comparison to be made between the plastic strain behavior of HSLA-100 steel and a traditional constitutive equation used to describe the stress-strain behavior of metals.

This book was released on 2017-10-16 with total page 58 pages. Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from Effect of Temperature, Deformation, and Rate of Loading on the Tensile Properties of Low-Carbon Steel Below the Thermal Critical Range It has long been known that increase in temperature above the ordinary atmospheric range is accompanied by changes in steels, particularly in strength and ductility. A large number of interesting and important papers dealing with various phases of this subject have appeared from time to time, but as recently pointed out by Jeffries our knowledge 15 still unsatisfactory, and a better understanding of these changes will undoubtedly be of benefit to industry. White (35) is of the opinion that our knowledge of the tensilgyproperties of steels at high temperatures is wholly inadequate: and has not kept pace with advancement of knowledge in other branches of engineering, while Howe (3 8) long 0 ago called attention to the apparent anomalies found in study ing the effects of work at temperatures under the thermal trans formations on the properties of wrought iron and steel used in boiler construction. Certainly, from the standpoint of engineering design, it is important to know the variations in limit of propor tionality with changes in temperature, but unfortunately this is the more difficult to determine of those factors considered in tensile tests, and the data available are conflicting.

Download or read book The Effect of Aging Treatment on the Microstructure and Properties of Copper Precipitation Strengthened HSLA High Strength Low Alloy Steel written by Martin H. Heinze and published by . This book was released on 1988 with total page 65 pages. Available in PDF, EPUB and Kindle. Book excerpt: The high strength low alloy (HSLA) steels which are being developed as replacements for the HY family of steels are low carbon steels which derive their strength in part due to the precipitation of fine coherent copper particles formed during a quench and aging heat treatment. HSLA-100 is being developed to meet the strength and toughness requirements of HY-100 but can easily welded without preheat, thereby reducing fabrication costs. This investigation uses light and electron microscopy for microstructural characterization while tensile, Charpy, and hardness tests are relied upon for the mechanical properties. The microstructure and mechanical characteristics of HSLA-100 after aging at several different temperatures was correlated. A high ductility and the minimum 100 ksi yield strength was found after aging at 675 C, although this temperature was found to be close to the low eutectoid temperature displayed by HSLA-100. Splitting was observed in the tensile fracture surfaces but the mechanical properties were not adversely affected. (jes).

This book was released on 2012-12-06 with total page 427 pages. Available in PDF, EPUB and Kindle. Book excerpt: Masters Theses in the Pure and Applied Sciences was first conceived, published, and disseminated by the Center for Information and Numerical Data Analysis and Synthesis (CINDAS)* at Purdue University in 1957, starting its coverage of theses with the academic year 1955. Beginning with Volume 13, the printing and dis semination phases of the activity were transferred to University Microfilms/Xerox of Ann Arbor, Michigan, with the thought that such an arrangement would be more beneficial to the academic and general scientific and technical community. After five years of this joint undertaking we had concluded that it was in the interest of all concerned if the printing and distribution of the volumes were handled by an international publishing house to assure improved service and broader dissemination. Hence, starting with Volume 18, Masters Theses in the Pure and Applied Sciences has been disseminated on a worldwide basis by Plenum Publishing Corporation of New York, and in the same year the coverage was broadened to include Canadian universities. All back issues can also be ordered from Plenum. We have reported in Volume 39 (thesis year 1994) a total of 13,953 thesis titles from 21 Canadian and 159 United States universities. We are sure that this broader base for these titles reported will greatly enhance the value of this impor tant annual reference work. While Volume 39 reports theses submitted in 1994, on occasion, certain uni versities do report theses submitted in previous years but not reported at the time.

Available in PDF, EPUB and Kindle. Book excerpt: The era of lean production and excellence in manufacturing, advancing with sustainable development, demands the rational utilization of raw materials and energy resources, adopting cleaner and environmentally-friendly industrial processes. In view of the new industrial revolution, through digital transformation, the exploitation of smart and sophisticated materials systems, the need of minimizing scrap and increasing efficiency, reliability and lifetime and, on the other hand, the pursuit of fuel economy and limitation of carbon footprint, are necessary conditions for the imminent growth in a highly competitive economy. Failure analysis is an interdisciplinary scientific topic, reflecting the opinions and interpretations coming from a systematic evidence-gathering procedure, embracing various important sectors, imparting knowledge, and substantiating improvement practices. The deep understanding of material/component role (e.g., rotating shaft, extrusion die, gas pipeline) and properties will be of central importance for fitness for purpose in certain industrial processes and applications. Finally, it is hoped and strongly believed that the accumulation of additional knowledge in the field of failure mechanisms and the adoption of the principles, philosophy, and deep understanding of failure analysis process approach will strongly promote the learning concept, as a continuously evolving process leading to personal and social progress and prosperity.

Download or read book Temperature Effects on the Mechanical Properties of Annealed and HERF 304L Stainless Steel written by Bonnie R. Antoun and published by . This book was released on 2004 with total page 38 pages. Available in PDF, EPUB and Kindle. Book excerpt: The effect of temperature on the tensile properties of annealed 304L stainless steel and HERF 304L stainless steel forgings was determined by completing experiments over the moderate range of -40 F to 160 F. Temperature effects were more significant in the annealed material than the HERF material. The tensile yield strength of the annealed material at -40 F averaged twenty two percent above the room temperature value and at 160 F averaged thirteen percent below. The tensile yield strength for the three different geometry HERF forgings at -40 F and 160 F changed less than ten percent from room temperature. The ultimate tensile strength was more temperature dependent than the yield strength. The annealed material averaged thirty six percent above and fourteen percent below the room temperature ultimate strength at -40 F and 160 F, respectively. The HERF forgings exhibited similar, slightly lower changes in ultimate strength with temperature. For completeness and illustrative purposes, the stress-strain curves are included for each of the tensile experiments conducted. The results of this study prompted a continuation study to determine tensile property changes of welded 304L stainless steel material with temperature, documented separately.
