Slow strain rate tensile tests on notched specimens of copper

Materials Science & Engineering A: Structural Materials: Properties, Microstructure and Processing, 2016
In this study, slow strain rate tensile tests have been performed on phosphorus alloyed copper under uniaxial and multiaxial stress states at 75 and 125 °C with two strain rates 10-6 and 10-7 s-1.

On the suitability of slow strain rate tensile testing for assessing hydrogen embrittlement susceptibility [PDF]

Corrosion Science, 2020
The onset of sub-critical crack growth during slow strain rate tensile testing (SSRT) is assessed through a combined experimental and modeling approach. A systematic comparison of the extent of intergranular fracture and expected hydrogen ingress suggests that hydrogen diffusion alone is insufficient to explain the intergranular fracture depths ...

Differences between internal and external hydrogen effects on slow strain rate tensile test of iron-based superalloy A286

International Journal of Hydrogen Energy, 2022
Abstract To investigate the evaluation method of hydrogen compatibility of A286 superalloy in high pressure hydrogen gas, SSRT tests of hydrogen-charged specimens were conducted at ambient temperature at various strain rates. The relative reduction in area (RRA), one of the ductility parameters, was determined.

Slow strain rate tensile tests on notched specimens of as-cast pure Cu and Cu–Fe–Co alloys

Journal of Alloys and Compounds, 2020
Abstract Microstructure evolution in the as-cast pure Cu, Cu-(1.0, 2.0, 3.0)Fe-0.5Co (wt. %) alloys were characterized in the former work. The aim of the present study is to investigate the slow strain rate tensile (SSRT) performance and fracture behavior of the Cu–Fe–Co alloys reinforced with fined grains (FG) and iron-rich nanoparticles (NP ...

Slow strain rate tensile tests on T91 in static lead–bismuth eutectic

Journal of Nuclear Materials, 2006
Abstract The embrittlement effect of liquid lead–bismuth eutectic (LBE) on martensitic steel T91 has been studied by performing slow-strain-rate tensile (SSRT) tests in static LBE with about 1 wppm oxygen at temperatures ranging from 250 °C to 425 °C. Two groups of samples were used.

Brittle fracture in 50Mo–50Re alloys during slow strain rate tensile testing

Philosophical Magazine, 2008
Tensile tests were conducted on 50 wt% Mo–50 wt% Re alloys in both fully recrystallized and recovery heat-treated conditions at a low strain rate of 10−6 s−1 and room temperature in air. It was found that both material conditions exhibited predominantly cleavage fracture with significant intergranular secondary cracking, compared to the predominantly ...

Investigation of the Effect of pH on Stress Corrosion Cracking of API 5L X65 Steel by Impedance Spectroscopy and Slow Strain Rate Tensile Test

Journal of Materials Engineering and Performance, 2021
In this study, impedance spectroscopy, slow strain rate tensile test, and scanning electron microscopy were used to investigate the susceptibility of API 5L X65 steel to stress corrosion cracking (SCC) in a sulfide brine solution with different pHs. According to the analysis of SSRT, steel was susceptible to SCC in a brine solution.
