Rippled Strain Rate Test for CRA Sour Service Materials Selection

Corrosion, 1997
To ensure economic and reliable materials selection it is necessary to evaluate corrosion resistant alloys (CRAs) under the most severe environmental and mechanical conditions that are realistically anticipated in service.

Applications of Slow Strain Rate Testing in the Nuclear Power Industry

1993
Slow strain rate (SSR) tests are widely used to evaluate materials for service in the nuclear power industry. The slow strain rate method is used to select new materials and to qualify heats of existing materials for use in components exposed to reactor coolant. Several different modifications of the SSR test have been developed over the

Slow-Strain-Rate Testing of Al 7075-T6 in Controlled Atmospheres

1984
The stress-corrosion-cracking (SCC) susceptibility of Al 7075-T6 alloys has been studied in a controlled-atmosphere chamber utilizing the slow-strain-rate technique. The effects of high-humidity air with small additions of sulfur dioxide, nitrogen dioxide, and surface salts in different combinations have been investigated to predict the behavior of ...

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.

Slow strain rate stress corrosion testing at elevated temperatures and high pressures

Corrosion Science, 1980
Abstract Slow strain rate stress corrosion cracking experiments have been performed on single phase and duplex phase 304 stainless steels at 290°C. Environmental variables included chloride concentrations (0–1000 ppm), oxygen concentration (0–2 ppm) and potential ( ϕ corr to + 500 mV vs Ag/AgCl). These experiments have shown that s.c.c.

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 ...

Application of Slow Strain Rate Test for SCC in Chemical Process Industries

CORROSION 1978, 1978
The slow strain rate technique is a method to evaluate the susceptibility of metals and alloys to stress-corrosion cracking (SCC). In essence, the slow strain rate technique comprises straining a metal specimen at a slow rate, typically 10-4 to 10-8/s, under controlled environmental conditions. Strain rates in the critical range to promote SCC maintain

Specimen size effects in slow strain-rate testing

2015
A study was conducted to evaluate the effect of specimen dimensions in slow strain-rate environmental effects testing. Tension tests of free machining brass were conducted in a mercuric nitrate solution at a constant crosshead displacement rate of 10⁻³(inch/sec). Thirty-six smooth round bar specimens with different dimensions were tested.

Evaluation of caustic embrittlement susceptibility of steels by slow strain rate testing

Metallurgical and Materials Transactions A, 2005
This article investigates applicability of slow strain rate testing (SSRT), which is a common testing technique for determining susceptibility to caustic cracking/stress corrosion cracking (SCC). The results suggest the need for investigating a wide range of strain rates, while investigating the role of other test/process variables.
