Effect of Slow Strain Rates on the Hydrogen Migration and Different Crack Propagation Modes in Pipeline Steel

Steel Research International, 2023
The slow‐strain‐rate test (SSRT) is the most commonly used method for evaluating pipeline steel in service environments. However, to accurately assess the sensitivity of steel to hydrogen, it is necessary to investigate the effect of different strain ...

Portable Slow Strain-Rate Stress Corrosion Test Device

1979
A portable test device has been constructed for determining the stress corrosion cracking (SCC) characteristics of process environments. The device may be inserted and retrieved from laboratory, plant, and field equipment operating at pressures up to 13.8 MPa (2000 psi) and temperatures not exceeding 204°C (400°F) without shutting down the system ...

Slow Strain-Rate Testing in High Temperature Water

1979
The apparatus and technique employed in slow strain-rate testing of stainless steels in high temperature high purity water are described and discussed. Typical results from work in progress on the influence of heat treatment and surface treatment on the intergranular stress corrosion cracking of Types 304 and 308 stainless steel and Alloy XM-19 are ...

Slow strain rate tensile tests on notched specimens of copper

Materials Science and Engineering: A, 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.

Application of Visual Basic in Fluctuant Slow Strain Rate Test

Applied Mechanics and Materials, 2014
With the example of stress corrosion test of natural gas pipeline steel, the application of Visual Basic (VB) language program in the test will be discussed in the paper. The result shows that different waveforms of VB language design can simulate various forms of applied load of pipeline steel well, and make fluctuant slow strain rate test more ...

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.

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

Evaluation of Slow Strain-Rate Stress Corrosion Tests Results

1979
Slow strain-rate technique provides a rapid and reliable method to determine stress corrosion cracking (SCC) susceptibility of metals and alloys for a broad range of applications. Procedures are discussed for using the technique to (a) determine if an alloy is susceptible to SCC, (b) express SCC severity quantitatively, (c) rank alloys with respect to ...

Multispecimen Test Facility for High Temperature, High Pressure Slow Strain-Rate Testing

1979
This paper describes a slow strain-rate test facility in which 6 tension specimens may be tested simultaneously and load-versus-displacement curves for each specimen may be recorded. The facility is designed to operate at a maximum temperature of 500 K (450 °F) and a maximum pressure of 28 MPa (4 ksi). Constant crosshead displacement rates ranging from
