Slow Strain Rate Testing—25 Years Experience

1993
The development of slow strain rate testing for environment sensitive cracking over the last 25 years is reviewed. In its original form, in which specimens are continuously strained to total failure, the method is still valuable, especially as a rapid sorting approach to the effects of metallurgical or environmental changes in systems, and examples are

Hydrogen Embrittlement of AISI 4340 Using Slow Strain Rate Testing

CORROSION 2014, 2014
Abstract Hydrogen embrittlement of AISI 4340 was studied using slow strain rate tests of smooth dog-bone geometry specimens. Two heat treatments were evaluated that produced yield strengths of 1479 MPa (215 ksi) and 1140 MPa (165 ksi). The strain rate over the gauge section for the smooth tests was 1x10-6 s-1.

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

A Bursting Tube, Slow Strain-Rate Stress Corrosion Test

1979
The construction of a facility to perform slow strain-rate stress corrosion tests by slowly increasing the pressure in a tubular specimen is described. Advantages of this bursting tube stress corrosion test are outlined and preliminary results reported.

Fracture Analysis of Slow Strain Rate Test for Stress Corrosion Cracking

CORROSION 2009, 2009
Abstract Slow-Strain-Rate (SSR) tests are usually limited to comparative evaluations of Stress Corrosion Cracking (SCC) based on relative changes in ductility parameters such as elongation and reduction in area. Recently Crack Growth Rate (CGR) and Threshold Stress Intentisity Factor (KISCC) analyses of data from SSR tests have been used

Laboratory Compression Tests of Sea Ice at Slow Strain Rates From a Field Test Program

Journal of Offshore Mechanics and Arctic Engineering, 1988
In the winter of 1979/80, five petroleum companies participated in a field test program conducted by Exxon Production Research Company in Prudhoe Bay, Alaska, to measure the unconfined compressive strength of the sea ice sheet in its full thickness at various strain rates between 10−7 and 8 × 10−5 s−1. As part of this program, ice sample blocks at four

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 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 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.

Slow Strain Rate Testing of Alloy 22 in Simulated Concentrated Ground Waters

CORROSION 2004, 2004
Abstract The proposed engineering barriers for the high-level nuclear waste repository in Yucca Mountain include a double walled container and a detached drip shield. The candidate material for the external wall of the container is Alloy 22 (N06022).
