Download or read book Effect of Microstructure on Fatigue Crack Growth of 7XXX Aluminum Alloys Under Constant Amplitude and Spectrum Loading written by T. H Sanders (Jr) and published by . This book was released on 1978 with total page 252 pages. Available in PDF, EPUB and Kindle. Book excerpt: An investigation was made to identify microstructural features which control the fatigue crack growth characteristics of 7XXX aluminum alloys. Constant amplitude and simple overload tests were conducted in humid air on controlled microstructural variations of alloys 7075 and 7050. Results indicated that relative influence of different microstructural features and ranking of the alloys based on fatigue crack propagation resistance depend on loading conditions.
