Download or read book Electron Microscope Fracture Examination to Characterize and Identify Modes of Fracture written by C. D. Beachem and published by . This book was released on 1965 with total page 132 pages. Available in PDF, EPUB and Kindle. Book excerpt: The fine-scale fracture topographies of both monotonic and fatigue fracture surfaces of several steels and aluminum and titanium alloys have been characterized. Some effects of orientation of specimen upon the fatigue crack surface appearance in 2024 T851 were found. Quasicleavage in hydrogen embrittled, 250,000 psi yield strength, maraging steel was discovered. Four overload fracture modes, including a previously unreported mode, were found in a 7075 T6 aluminum alloy by precision matching techniques. A number of failure analyses were made. (Author).
