Axial load fatigue crack propagation tests were conducted on notched sheet specimens made of 1100 aluminum alloy. These tests were made at stress ratios (ratio of the minimum stress to the maximum stress) ranging from −0.5 to 0.5 in order to study the effects of stress ratio on fatigue crack growth. Experimental fatigue crack propagation data were analysed using Paris-Erdoǧan stress intensity analysis. The data from the tests at different stress ratios showed that two regions, namely, region I and region II were present.

CRACK-GROWTH KINETICS OF 7050-T73651 ALUMINUM-ALLOY UNDER CONSTANT LOAD AT 150-DEGREES-C SARIOGLU, F; ABACHI, P; DORUK, M (Springer Science and Business Media LLC, 1993-03-15) Crack growth tests at 150-degrees-C under constant load conditions were performed on compact tension specimens of 7050-T73651 aluminium alloy. The d.c. potential drop method was employed to monitor crack lengths throughout the tests. Fracture mechanics parameters such as the stress intensity factor (K) and energy-rate line integral (C*) were used to establish correlation with the crack propagation rates. As a result of experiments it was found that crack growth rates (da/dt) versus K, over discrete ranges o...
Effect of Sm on thermal and mechanical properties of Cu-Zr-Al bulk metallic glasses Sikan, Fatih; Atabay, S. E.; Motallebzadeh, A.; Özerinç, Sezer; Kalay, I.; Kalay, Yunus Eren (Elsevier BV, 2019-01-16) The effect of rare-earth (Sm) microalloying on the thermal stability and phase selection along with the effect of nanocrystallization on the mechanical properties of amorphous melt-spun ribbons of Zr50Cu40Al10, Zr49Cu39.2Al9.8Sm2 and Zr48Cu38.4Al9.6Sm4 alloys were investigated using differential scanning calorimetry (DSC), X-ray diffraction (XRD), transmission electron microscopy (TEM), Vickers and nanoindentation hardness tests and micropillar compression analysis. XRD and TEM analyses showed that all samp...
Effect of microstructural modification on damage tolerance of 34CrMo4 shaft steel Ozcan, Burak; Gurer, Goksu; Gür, Cemil Hakan (Wiley, 2020-06-01) Overall damage tolerances of the heat-treated 34CrMo4 steels having ferritic-pearlitic, bainitic, and tempered-martensitic microstructures were evaluated based on their threshold stress intensity factor prior to small crack propagation, fatigue strength, and fracture toughness under static loading. Kitagawa-Takahashi diagrams were constructed to determine the limiting size of small crack propagation. The micromechanical effects of carbide morphology and phase distribution on quasi-static and dynamic mechani...
Effect of Microstructure on the Mechanical Behavior of Reactive Magnetron Sputtered Al2O3/TiO2 Multilayer Ceramics Dericioğlu, Arcan Fehmi (Japan Institute of Metals, 2008-11-01) Mechanical characteristics of reactive magnetron sputtered Al2O3-TiO2 multilayer ceramics were studied. Tailored mechanical properties such as moderately high hardness and reasonable toughness were achieved through varying sputtering process parameters resulting in microstructural control at nano-scale. Interchanging Al2O3 and TiO2 layers with a single layer thickness of similar to 65-70 nm were deposited on single crystal alumina (sapphire) substrates to form the multilayer structure composed of 10 layers....
Effect of carbon fiber amount and length on flame retardant and mechanical properties of intumescent polypropylene composites ATABEK SAVAŞ, Lemiye; Mutlu, Aysenur; Dike, Ali Sinan; Tayfun, Umit; DOĞAN, Mehmet (SAGE Publications, 2018-02-01) The effects of carbon fiber amount and length were studied on the flame retardant, thermal, and mechanical properties of the intumescent polypropylene composites. The flame retardant properties of the intumescent polypropylene-based composites were investigated using limiting oxygen index, vertical burning test (UL-94), and mass loss calorimeter. The mechanical properties of the composites were studied using tensile test and dynamic mechanical analysis. According to the flammability tests results, the antag...
