This book was released on 1986 with total page 20 pages. Available in PDF, EPUB and Kindle. Book excerpt: Small punch tests were developed to determine the ductile-brittle transition temperature of nickel-chromium (Ni-Cr) steels having various degrees of temper embrittlement and various microstructures. It was found that the small punch test clearly shows the ductile-brittle transition behavior of the temper-embrittled steels. The measured values were compared with those obtained from Charpy impact and uniaxial tensile tests. The effects of punch tip shape, a notch, and the strain rate on the ductile-brittle transition behavior were examined. It was found that the combined use of a notch, high strain rates, and a small punch tip strongly affects the ductile-brittle transition behavior. Considerable variations in the data were observed when the small punch tests were performed on coarse-grained steels. Several factors controlling embrittlement measurements of steels are discussed in terms of brittle fracture mechanisms.

Download or read book Advances in Material Property Characterization using Small Punch Tests written by Bijan Kumar Dutta and published by CRC Press. This book was released on 2024-11-08 with total page 195 pages. Available in PDF, EPUB and Kindle. Book excerpt: The small punch test (SPT) is useful to calculate changes in the tensile and fracture properties of structural materials during the service life of the materials of plant components. This book compiles advances in the development of correlations to calculate mechanical properties of the materials using SPT data. New correlations have been developed using hybrid methodology involving analytical and experimental data. The newly developed correlations have been tested conducting case studies on SPT and pre- cracked/ notched SPT (p- SPT) specimens. The eventual applications of all the new correlations have been demonstrated by conducting a real- life case study involving degradation of structural material from ductile to semi- brittle state due to aging. Features: • Presents exclusive material on the remnant life assessment of in- service materials using SPTs. • Assesses the fracture toughness of ductile materials using the experimentally measured biaxial fracture strain. • Provides new equations to calculate the yield and ultimate stresses of copper and titanium alloys using measured SPT data. • Explores functions to correlate the load- displacement data of p- SPT specimens with fracture properties. • Includes case studies with direct relevance to the degradation of plant materials. This book is aimed at researchers, professionals, and graduate students in materials science and engineering, mechanical property characterization and testing, and small- scale experimentation. It is expected that the advanced methodology presented in this book to evaluate changes in the properties of aged materials during the service life using SPT data are useful to designers for safety evaluation and also to calculate the remaining service life of industrial components for life extension studies.

Available in PDF, EPUB and Kindle. Book excerpt: This book is a comprehensive overview of methods of characterizing the mechanical properties of engineering materials using specimen sizes in the micro-scale regime (0.3-5.0 mm). A range of issues associated with miniature specimen testing like correlation methodologies for data transferability between different specimen sizes, use of numerical simulation/analysis for data inversion, application to actual structures using scooped out samples or by in-situ testing, and more importantly developing a common code of practice are discussed and presented in a concise manner.

Available in PDF, EPUB and Kindle. Book excerpt: As part of an increasing interest in radiation embrittlement for aging nuclear reactors, scientists gathered in New Orleans in January 1997 to consider the interests and capabilities of the scientific-testing community and of the commercial light-water-cooled power-reactor industry in terms of improving methods to characterize component integrity. The resulting 37 papers concentrate on the use of unique small and miniature specimens; nondestructive, nonintrusive, and in- situ test techniques for measuring mechanical and fracture properties; the application of tests to irradiation-induced embrittlement; and actual examples of tests to determine material integrity and to evaluate potential component life extension. They consider experimental, analytical, and computational aspects. Annotation copyrighted by Book News, Inc., Portland, OR

Download or read book Development of a Multiple Linear Regression Model to Estimate the Ductile Brittle Transition Temperature of Ferritic Low Alloy Steels Based on the Relationship Between Small Punch and Charpy V Notch Tests written by ML. Saucedo-Muñoz and published by . This book was released on 2000 with total page 7 pages. Available in PDF, EPUB and Kindle. Book excerpt: The transition temperatures of Cr-0.5Mo, Cr-Mo, and Cr-Mo-V steels were determined using the Charpy V-notch (CVN) and the small punch (SP) tests. It was confirmed that there was a linear correlation between the transition temperature of ductile-brittle behavior determined by the Charpy V-notch test and that obtained from the small punch test. However, the estimation of CVN transition temperature by means of this linear equation is not completely reliable because of the large experimental scatter of data. In order to improve the reliability of the transition temperature estimation, a multiple linear regression (MLR) analysis was conducted to evaluate the effect of different variables of the manufacturing process and service conditions. This analysis permitted the determination of the following regression equation: CVNDBTT=1.35SPDBTT-0.84x103d-1/2+326. This equation enables one to assess more accurately the transition temperature corresponding to the Charpy V-notch test using that of the small punch test and the austenitic grain size, expressed by d-1/2.

Download or read book Determination of Ductile Brittle Transition Temperature DBTT in Dynamic Small Punch Test written by Y-H Joo and published by . This book was released on 1992 with total page 9 pages. Available in PDF, EPUB and Kindle. Book excerpt: A dynamic small punch test technique is demonstrated for measuring the ductile-brittle transition temperature (DBTT) of aged Cr-Mo-V turbine rotor steels. Based on fracture energy measurements and fracture surface observations it is shown that the dynamic small punch test specimens exhibit a clear ductile-brittle transition behavior. The DBTT can be determined reliably by statistically analyzing the scatter in the fracture energy data and by defining the fracture appearance transition temperature. The measured values of DBTT are compared with those obtained from Charpy impact tests.

Available in PDF, EPUB and Kindle. Book excerpt: Advances in Hydrogen Production, Storage and Distribution reviews recent developments in this key component of the emerging "hydrogen economy," an energy infrastructure based on hydrogen. Since hydrogen can be produced without using fossil fuels, a move to such an economy has the potential to reduce greenhouse gas emissions and improve energy security. However, such a move also requires the advanced production, storage and usage techniques discussed in this book. Part one introduces the fundamentals of hydrogen production, storage, and distribution, including an overview of the development of the necessary infrastructure, an analysis of the potential environmental benefits, and a review of some important hydrogen production technologies in conventional, bio-based, and nuclear power plants.
