High-carbon structural steel wires were prestressed to various levels in a plasma hydrogenation environment and then pulled slow strain rate test (SSRT). The effect of under different prestressing on the material's tensile response hydrogen embrittlement was noted. It found that ultimate strength (UTS), yield strength, ductility wire samples are decreased by levels. more drastic decrease UTS, i...

In this study, A2017-T4 aluminum alloy was plated with electroless Ni–P different phosphorus content and rotary bending fatigue test conducted to investigate the effect of hydrogen by plating on properties. The strength low-phosphorus type specimen higher than that untreated specimen, while high-phosphorus much lower. It is clear differs greatly depending in film. decrease high attributed induc...

Abstract The effect of Cl − concentration on stress corrosion cracking (SCC) susceptibility high manganese steel was investigated by slow strain rate tensile (SSRT) test, electrochemical and immersion test in different NaCl solutions. results show that the SCC first increases then decreases with increase concentration. When 10.5%, highest, fracture showed river-like transgranular quasi-cleavage...

We evaluated and modeled the viscoelastic characteristics of chitosan and chitosan-gelatin scaffolds prepared using a freeze-drying technique. Chitosan and chitosan-gelatin solutions (0.5 and 2 wt.%) were frozen at -80°C and freeze-dried. Using the scaffolds, uniaxial tensile properties were evaluated under physiological conditions (hydrated in phosphate buffered saline at 37°C) at a cross-head...

conventional investigations on the behavior of reinforced and unreinforced soils are often investigated at the failure point. in this paper, a new concept of comparison of the behavior of reinforced and unreinforced soil by estimating the strength and strength ratio (deviatoric stress of reinforced sample to unreinforced sample) at various strain levels is proposed. a comprehensive set of labor...

in the hot compression test friction has a detrimental influence on the flow stress through the process and therefore, correcting the deformation curve for real behavior is very important for both researchers and engineers. in this study, a series of compression tests were simulated using abaqus software. in this study, it has been employed the taguchi method to design experiments by the factor...
