THERMAL FATIGUE RESISTANCES OF 356 AND 413 CAST Al ALLOYS
Abstract: Thermal fatigue is a stochastic process often showing considerable scatter even in controlled environments. Due to complexity of thermal fatigue, there is no a complete analytical solution for predicting the effect of this property on the life of various components, subjected to severe thermal fluctuations. Among these components, one can mention car cylinder, cylinder head and pi...
متن کاملOptimization of Process Parameters of Electron Beam Welded Fe49Co2V Alloys
Electron beam welding has shown a remarkable job in the space industry for welding of components. It is performed under a vacuum environment that eliminates foreign matter such as hydrogen, oxygen, and other gases. Joining of similar and dissimilar materials is the main advantage of electron beam welding with high depth to width ratio as well as sharp focus at the point where parts are to be we...
متن کاملCharacterizing Fatigue and Fracture Response of Medical Grade Nickel-Titanium Alloys by Rotary Beam Testing
With respect to a dynamic test protocol, fatigue information has been reliable in predicting wire wear longevity as well as critical structural integrity. It has been noted that the efficacy of modern medical devices are confined by the life cycle of the material of which they are composed. The aim of this study is to expound on the means of how rotary beam fatigue test methods merit attention ...
متن کاملCharacterizing Fatigue Response of Nickel-Titanium Alloys by Rotary Beam Testing
Fatigue information has been reliable in predicting wire critical structural integrity. The aim of this study is to expound on the characterization technique of rotary beam fatigue testing RBT . By alternating tension and compression stress states through RBT, it is possible to determine the life expectancy of Nitinol monofilament round wires. Fatigue testing has been employed to characterize t...
متن کاملCORROSION FATIGUE CRACK PROPAGATION AND INHIBITION IN Al-Zn-Mg-Cu VS Al-Cu-Mg/Li ALLOYS
Age-hardenable aluminum alloys used in aerospace structures are susceptible to environment assisted fatigue crack propagation (EFCP), limiting component durability and safety. The objective is to quantitatively understand EFCP and its inhibition for important aerospace alloys: 7075-T651 (Al-Zn-Cu-Mg), C433-T3 (Al-Cu-Mg), and C47A-T86 (AlCu-Li). EFCP is understood through the hydrogen embrittlem...
