This book was released on 1977 with total page 24 pages. Available in PDF, EPUB and Kindle. Book excerpt: The fracture surfaces of fatigue specimens of Type 316 stainless steel previously tested at elevated temperatures in air have been examined by scanning electron microscopy (SEM) to characterize the failure processes and to establish correlations with the previous studies of fatigue crack propagation. The SEM observations show three significantly different types of behavior which can be explained in terms of the differences in materials processing history and test conditions. Solution-annealed material tested at 800 F (427 C) exhibits a transgranular failure mode with fatigue striations indicative of a ductile failure process. Solution-annealed material tested at 1100 F (593 C) shows a change in failure mode to partially intergranular failure and an increase in crack propagation rate relative to the tests at 800 F (427 C). Imposition of a hold time further increases the proportion of the surface characterized by intertranular failure, and the crack growth rate also increases. Material aged at 1100 F (593 C) and tested at 1100 F (593 C) shows a return to the transgranular failure mode and a lower crack growth rate than solution annealed material tested at 1100 F (593 C). The imposition of a hold time period had no significant effect on the failure mode. The observations are consistent with a model in which grain boundary embrittlement caused by diffusion of oxygen ahead of the crack tip produces intergranular failure and an acceleration of crack growth rate.

Download or read book Fatigue Failure of Metals written by S. Kocanda and published by Springer. This book was released on 1978-04-30 with total page 398 pages. Available in PDF, EPUB and Kindle. Book excerpt: The studies on the phenomena of fatigue in metals, and especially on the formation and growth rate of cracks have been conducted in 1972-1974 with continued intensity. Their results contribute to expanding our knowledge and give us a new insight into the sphere of metal fatigue which is a highly interdiscipline field. This makes the continuous amending and modifying of books on metal fatigue a necessity, unfortunately often related with the not easy task of changing one's opinions and critical analysis of established earlier notions. These aims were my chief concern when preparing the present edition of my book in which I made use of carefully selected new information from 1972-1973 and partly 1974 reports. This new matter has been included in many instances just to signal new facts or findings, since the limited space did not allow me to give them the amount of consideration they deserve. The book has been further supplemented with the results of micrographic studies conducted in co-operation with J. Kozubowski for which lowe him special thanks. I am also indebted to Mr. H. Mughrabi from Stuttgart for allowing me to publish in this book his very interesting micrographs of dislocation structures. Finally I should like to express my sincere thanks to Mr. E. Lepa for his concern in producing a good English translation of my book.

Book excerpt: NSA is a comprehensive collection of international nuclear science and technology literature for the period 1948 through 1976, pre-dating the prestigious INIS database, which began in 1970. NSA existed as a printed product (Volumes 1-33) initially, created by DOE's predecessor, the U.S. Atomic Energy Commission (AEC). NSA includes citations to scientific and technical reports from the AEC, the U.S. Energy Research and Development Administration and its contractors, plus other agencies and international organizations, universities, and industrial and research organizations. References to books, conference proceedings, papers, patents, dissertations, engineering drawings, and journal articles from worldwide sources are also included. Abstracts and full text are provided if available.
